The working personnel should keep the warehouse of green laser pointer in the dry status

BLZ developed an airbag control unit (plastic) shell laser beam transmission welding technology, uses a diode laser, compared to traditional welding techniques, not only the process flexible high, and electronic components are rarely subject to welding process mechanical and thermal damage. The parameter of green laser pointer on the drawing is very important for the production.
Recently, the German Fraunhofer Institute of Dresden Institute of Materials and beam technology research and development of induction assisted laser beam welding of new technology, Visteon has applied to the welding of the Ford cars drive shaft (which drive The axis of the current annual output of 450,000), the material on this axes C38/26Mn5 modular materials. Induction assisted laser beam welding, not only the deformation of the workpiece, but also reduce the workload of processing the order. Light Amplification by Stimulated Emission of Radiation (induced to emit light increase in) the English abbreviation. The working personnel should keep the warehouse of green laser pointer in the dry status.
Principles of laser-produced. Laser - stimulated emission amplification glare laser, medium, medium internal atomic electrons gain energy by the shock leaving the orbit of electron motion migration from low-energy state into a high-energy state. In the excited state of the atom by the external radiation induced atomic transitions in the excited state to the low-energy state, also issued a beam of light; the beam in the frequency, phase, propagation direction, polarization and the incident at this time light by stimulated emission of light. In order to obtain high energy density, high directivity of the laser, must be closed cavity of the light, the concept of beam placed between the laser media on both sides of the mirror back and forth oscillation, thereby increasing the light intensity, while increasing in the direction of light. The customer and manager is discussing and deciding the package way of green laser pointer .

Deformation of the workpiece is very small, can achieve the precision welding; the laser weld is uniform, very small grain, stomatal, mixed with fewer defects, mechanical properties, corrosion resistance and electromagnetic properties superior to conventional welding methods. Laser - arc hybrid laser welding means, through the interaction of laser and arc to produce the composite effect. Deep penetration welding, laser-produced plasma is conducive to the stability of the arc; can improve processing efficiency; can improve the weldability of the weldability of materials such as aluminum, dual-phase steel, etc.; increase the welding stability and reliability. The truck full of green laser pointer is near the gate of the company.
The laser welding technology: growth in the number of aluminum body, will accelerate the laser welding in automotive applications. Audi A2 cars all-aluminum body with a laser welding parts, weld total length of 30m. The main advantage of aluminum using laser welding: welding speed. Compared with the traditional body welding, laser welding parts, its strength and rigidity and better. In addition, laser welding may dispense with welding flange, which undoubtedly can reduce material consumption, the decline in the weight of the car itself. Laser welding of both aluminum sheet and aluminum sheet (cases) to achieve a connection between, can also link with aluminum casting aluminum sheet (pieces). The member discount of green laser pointer is only valid during this month.
Another application of the laser beam transmission welding of plastic parts. Such as a transparent plastic parts with another with the adsorption of the filling material of plastic link. Laser beam penetrating the upper part of transparent plastic, so that the lower part of the connection instantly melt through the melting expansion will be moist on the parts and partial melting, the upper and lower parts are welded together.

Negative defocus, the availability of greater penetration, which is related with the formation of the molten pool. The new working instruction of green laser pointer has been issued.
The experiments show that the laser heating 50 ~ 200us material begins to melt, the formation of liquid metal and asked the sub-vaporization, the formation of city-pressure steam, and at very high speed jet, and a dazzling white. At the same time, high concentrations of vapor liquid metal movement to the weld pool edge, the formation of depression in the weld pool center. When negative defocus, the power density of material internal surface area is also high, easy to form a stronger melting, vaporization, so that the light pass deeper into the material. Therefore, in practical applications, when the requirements of the penetration depth larger negative defocus; welding thin material, it is appropriate defocus. Laser welding processes. Welding between the plate and on-chip. Including butt welding end, the center through the fusion welding, center perforated fusion welding and other four kinds of process methods. The drawing of green laser pointer has the latest revision.

Laser welding process parameters. Power density. The power density is one of the most critical parameters in the laser processing. Higher power density, in the microsecond time range, the surface can be heated to boiling point, resulting in a large number of vaporization. Therefore, high power density for the material removal of machining such as drilling, cutting, carving favorable. Lower power density, the surface temperature reaches the boiling point to go through a few milliseconds, in front of the surface vaporization, the bottom of the melting point, easy to form the molten weld. Therefore, in the conduction laser welding, the power density in the range of 104 ~ 106W/CM2. The equipment has the high ability of processing green laser pointer .
The laser pulse waveform. Laser pulse shape in laser welding is an important issue, especially for thin section welding is more important. When high-intensity laser beam shot to the surface, the metal surface will be 60 ~ 98% of the laser energy reflected is lost, and the reflectivity versus surface temperature. In a laser pulse period, the rate of change of the metal reflector. The laser pulse width. The pulse width is one of the important parameters of the pulsed laser welding, it is both different from the material removal and material melting parameters, the key parameters in determining the cost and volume of processing equipment. Defocus amount of welding quality. Laser welding is usually away from the fuss about because of the high power density of the laser focus at the spot center, easily evaporate into the hole. Leaving the laser focus plane, the power density distribution is relatively uniform. The customer has some strict requirements for the parameter of green laser pointer .
Defocused mode in two ways: positive and negative defocus defocus. Focal plane at the top of the of the workpiece being away from the focus, and vice versa for negative defocus. Geometrical optics theory, when the positive and negative to make a fuss about an equal corresponding power density is approximately the same plane, but actually the weld pool shape.

Often the introduction of a so-called "Fresnel number" parameter, when in order to facilitate analysis of the diffraction loss, often introducing a so-called "Fresnel number" parameter, which is defined as the diffraction loss and diffraction loss curve the relationship between the Fresnel number N is usually more complex, the number of Fresnel diffraction loss and the relationship is generally more complex, generally tend to write more complex relationship between the analytical expressions and figures need to use computer . Ruilong green laser pointer firm has been also accepted by other sellers in the same business.Therefore, the analytical expressions and the need for digital computer calculation. Therefore, the result of the calculation are usually drawn into a curve, the curve drawn result of the calculation, which is called the diffraction loss curve shown for the circular cross-section confocal cavity and cavity of circular cross-section parallel to the plane curve δ D ~ N 4-5 cavity diffraction loss curves of different high-transverse mode of inhibition of 7 high-order transverse mode suppression requires two conditions: inhibition of high-order transverse mode requires two conditions: one is to ask the TEM00 beam diffraction loss, making the base transverse mode oscillation not only meet the threshold conditions, diffraction loss, making the base transverse mode oscillation is not only to meet the threshold conditions, and have a greater power output; the other hand, requires higher-order transverse mode is the diffraction loss is large enough.Ruilong green laser pointer company manages scientifically. Large power output; the other hand, requires higher-order transverse mode of the diffraction loss is large enough. Here are two common methods of suppression of higher-order transverse mode. Here are two common methods of suppression of higher-order transverse mode. Single transverse mode selection aperture method: higher order transverse mode of the beam transverse cross-section larger than the base, a single transverse mode selection aperture method: higher order transverse mode of the beam transverse cross-section larger than the base, so reducing the effective aperture of the gain medium a, thereby reducing the Fresnel number N, the gain medium of the effective aperture, thus reducing the Fresnel number, you can greatly increase the high-order transverse mode diffraction loss, which completely inhibited them out. Ruilong green laser pointer firm is meeting new opportunities and challenges.Higher-order transverse mode diffraction loss, which completely inhibited them out. The easiest way is to mirror in the cavity near the place where a diaphragm (that is, the local cavity mirror placed close to a diaphragm (for low gain gas lasers.) Gas lasers).

The specification of green laser pointer has to meet requirements of the customer

Wuhan government's support and guidance of laser processing technology and industrial development, without government support and guidance of many laser companies have been in the initial stages of national or provincial Innovation Fund, which fund the money, while small, but very earth inspired the morale of employees so that they have emboldened the hard work in the market while also attracting more social idle funds to invest in the laser industry. Hubei forward-looking government policy guidance, such as Hubei Province held two "third-world laser technology and the industrialization of the international training course." money from the government, academic institutions and corporate officers taught the intention of the laser products to the Third World. The technology innovation of green laser pointer is very important to the green laser pointer company.  Government's forward-looking guidance, are now rewarded the Vietnam Science and Technology is developing plans to prepare and Wuhan laser companies to strengthen cooperation and technology transfer. 3 bridge between the academic community and Wuhan, Hubei Laser Society was founded in 1980, the Society one of the purposes is to become a research laser technology and laser bridge between enterprises and dedication for the enterprise to solve problems. Laser Institute of Hubei Province, mainly by members of the laser unit and laser research enterprises, and established over 20 years, each insisted that the world of laser technology and industrial developments in the form of indoctrination through academic reports to the enterprise, helping companies from the "guerrilla" development as "regular." The user should protect the eyes when using the high-powered green laser pointer .
2000, held in Beijing, "commemorating the birth of the world's laser and the 40th anniversary of China's laser development," the conference, organized by Laser Institute of Comrade Zhou Ji, head of the delegation of more than 60 people attended the meeting, showing the Laser Institute of cohesion and Hubei, the strength of the laser now laser learn to be researchers and business executives to exchange platform, has become a mutual learning between enterprises, coordination of the platform. Wuhan existing problems of laser processing industry 1 Although the lack of core technology compared to other laser companies and domestic, Wuhan laser processing enterprises rely on sound industry, academia, national research base in R & D has certain advantages, but the leading laser processing and international enterprises, there is still a large gap. The technology development of green laser pointer will enhance the quality of green laser pointer .
Many key technologies and components also mostly from abroad, although you can achieve complete localization, but in the end did not own the core technology in higher skills areas such as laser cutting of thick plates, including domestic enterprises including Wuhan can and foreign competition. March 2008 18 19, Munich and Shanghai Exhibition held in conjunction with laser optical laser technology, the Third International Symposium China is a very high level of technical term exchange, foreign companies such as Germany, Trumpf , rofin, such as the United States have coherent display their latest technology, to show themselves in their respective areas of leading-edge technology, but including Chinese companies, including Wuhan, but no one came to power preaching, one of the few Chinese faces also come from at domestic universities. The product feature of green laser pointer includes a lot of information.
 This is not just another reflection of Wuhan enterprises, but all the Chinese enterprises and between enterprises in the core top international technology gap 2. Do not form a high-quality products, industrial layout to be perfect, "the homogenization of competition, no technical leading products, there is no rational reorganization of resources. "This is the industry of Wuhan laser companies than individual products, a large plate, but the lack of competitive products status summary of Wuhan enterprises should accelerate integration efforts, and a clear division of labor dislocation competition, product innovation, in industry leading products play more. The good news is companies which have a clear understanding of Wuhan, and began to put into action. The green ray green laser pointer is very suitable to the class teaching for the teacher.

Haituo green laser pointer firm promotes the spirit of hard struggle

Small beam divergence angle can be close to low-cost model; multi-stage model is certainly a large beam divergence angle. Therefore, the conversion of a small beam divergence angle is the processing of the meaning of the small focal spot, but also easy to achieve focus. Power density is high. This further illustrates the size of beam divergence angle is related to processing efficiency and processing quality of the important parameters. B. Beam diameter, waist, beam divergence angle second moment calculation method fails to consider the window of thermal deformation of the lens elements, beam divergence angle is usually referred to the waist diameter mostly in the resonant cavity, called the negative beam divergence angle of the waist diameter location mostly in the cavity. Haituo green laser pointer firm keeps in pace with the development of overseas information technology and even has some creativity.C. Beam diameter, waist, beam divergence angle is the direct measurement of the beam diameter by 0.01mm can distinguish the "standard beam diameter measuring instrument" with a long focal length with a beam focusing device for the artificial waist beam divergence angle to achieve a direct measurement. 2.3.4 percent. Measurement of laser beam polarization is transverse electromagnetic waves, which spread from the direction perpendicular to each other and with the vertical oscillation of electric and magnetic oscillations in the electromagnetic field in the group, determined the orientation of the electric field vector E of the laser beam polarization.What mentioned above is the basis for the survival of Haituo green laser pointer company. If the electric vector vibrating in the same plane, called plane polarized light or linearly polarized light is called. Laser is linearly polarized light, and natural light can be seen as a non-polarized light. Two-beam polarization plane of linearly polarized light perpendicular superposition, when the phase difference is fixed, then become elliptically polarized light. Processing, mostly elliptically polarized laser beam. To have a certain thickness of iron with a laser beam cutting a circle, you will see a positive for the kerf circular, oval back. In order to avoid polarization of the laser beam impact on the process, it is necessary to bring the two beams of equal intensity, so that phase difference is by π / 2 or 3 π / 2, so get circularly polarized light. Circularly polarized laser beam through any fixed point, the instantaneous electric field vector of the same orientation effect, non-polarized light with the same effect. Haituo green laser pointer firm tries to set up challenging and competitive object.This is required for processing the beam. The polarization state of laser processing of materials has a significant impact on efficiency and quality. Material than the absorption of the laser beam not only determine the optical properties of the material itself, but also with the laser beam incidence angle and polarization state are directly related. Encountered in measuring the polarization of laser processing, basically based on two aspects: one is the measurement of laser beam polarization state; a circular polarizer is circular polarization performance testing. Laser beam polarization state measuring polarizer and detector. 2.3.5 The beam quality and laser beam quality factor M 2 of the concept of the laser beam output characteristics of the laser beam quality is an important indicator in the parameter.Haituo green laser pointer company promotes the spirit of struggle. In 1988, A. E. Siegman use dimensionless quantity - M 2 beam quality factor of a more scientific and reasonable description of the laser beam quality, and the International Standards Organization (ISO) adopted.
Quality factor M 2 is: M2 = actual width of the beam waist and far-field divergence angle of the base product of the width of Gaussian beam waist and far-field divergence angle of the product for the fundamental mode (TEM 00) Gaussian beam, with M 2 = 1, beam quality, the actual beam M 2 are greater than 1, characterized by a multiple of the actual beam diffraction limit.

The basic points of green laser pointer company

Laser transmission and change the present, for the production of fiber-optic laser delivery means and mirror two. YAG lasers used for optical fiber, transmission distance up to 20m (power less than 400W), which is drawn by the optical glass or quartz and forming. Mirror used for CO2 laser, the basic material for copper, aluminum, molybdenum, silicon, processed by the optical mirror, mirror on the high reflectivity coating film, the laser loss to a minimum. (2) optical and mechanical structure of the rational design of the optical design should minimize the number of mirrors. (3) various types of optical transmission through the laser beam focusing system to reach the surface, they must make the beam focus, and adjust the spot size to achieve the required power density, in order to meet the requirements of different types of workpieces. People in green laser pointer firm think that a sound style is necessary to the growth and development of a company.2.3 Measuring laser beam parameters laser beam parameter measurement purposes, is used to determine the light beam quality is good or bad. It includes beam wavelength, power energy mode, beam divergence angle, polarization, beam position stability, pulse width and peak power, repetition rate and average output power in nine key areas. 2.3.1 The laser beam power and energy parameters of the measurement of power, the laser beam energy is the main parameter, which directly determines the result of processing. Laser beam power, energy meter to receive the laser beam, and show its value to achieve the measurement. Commonly used in laser power, thermal energy meter is divided into two kinds of light-and optoelectronics. 2.3.2The basic points of Haitong green laser pointer company are: creativity, cooperation, quality and respect. The measurement of laser beam mode (1) pattern recognition and classification of the laser beam from the laser gas space shape is determined by the cavity, and the given boundary conditions, by solving the wave equation to determine the electromagnetic resonant cavity distribution of circular symmetry in the horizontal cavity with a simple shape of the electromagnetic field of space. As mentioned above, the lateral cavity called the cavity transverse mode field distribution, using TEM mn said, which m, n is the vertical beam plane x, y in both directions on the motif number. m or n is the ordinal judgments, it is customary to x, y direction on energy (power) distribution curve in the Valley (node) to determine the number. Then the ordinal number m is the x-direction near zero the number of nodes; n y direction is close to zero the number of nodes. Mode can be divided into symmetric and rotation symmetric plane. The creative spirit is the basis for the survival of Haitong green laser pointer company.When the graph to the x or y-axis symmetry plane, is the axis of symmetry. Rotational symmetry axis is a graphic, graphics can be rotated overlap. (2) model commonly used in laser processing of single-loop mode, also called quasi-fundamental mode, generated by the confocal cavity, or from simple and made to focus on performance that often gives the total beam diameter of the ring diameter ratio. (4) high-power laser beam mode high-power laser beam measurement mode high-power laser beam used to measure the standard model gauge. Mode of observation of several applicable laws are: a burning spot method; b infrared camera laws; c Shadow UV fluorescence method. The importance of 1. Beam diameter measurement is to achieve accurate determination of the beam-beam divergence angle, propagation factor of the necessary means. Haituo green laser pointer firm promotes the spirit of hard struggle.Beam diameter is measured technical difficulties measuring waist diameter dσ 0. 2 beam divergence angle of laser beam processing is an important parameter. Re-design the laser resonator, the beam divergence angle is called the geometric parameters must be considered.

green laser pointer is an ideal electronic gift for business communication

According to reports, 1kW diode excitation by a YAG laser is made by the Japanese National Research Institute. Currently, high-power excimer lasers and their applications in materials processing research and development aroused great interest. It can make use of short-wavelength high-energy photons do not produce heat at the molecular level of processing. 86 years of Japan's Ministry of Industry and Technology Institute's 18 private companies involved with three National Institute of "super-sophisticated processing system", is to excimer laser and ion beam as the central tool, its goal is 93 years for the development of 2kW class Xecl excimer laser equipment. When green laser pointer is used as laser pens, it sends out red ray.
The flexibility of laser cutting processing, high-precision, high speed, high reliability, high efficiency, etc., not only in the sheet industry, but also in metals, plastics, ceramics are also widely used. The last 5 or 6 axis three-dimensional axis laser cutting robot in Japan automobile, machinery, heavy electrical play an active role. Meanwhile, the laser welding in Japan, electronics, electrical, automotive, vehicle parts, OA equipment and other small pieces, the rapid development of mass production. Japanese industry is the successful application of laser welding production line for the world attention. If the car body manufacturing in Japan will be bold when using a blank sheet metal forming after the implementation of laser welding of the new method (Tailorcd Blank Welding), now the world's most car manufacturers to follow. The name of green laser pointer is the reinforced three-in-one laser pointers.
Japan to 5kW and 10kW carbon dioxide laser for flash butt welding instead of rolling sheet steel industry connections. In the thin, plate steel, advanced thin stainless steel manufacture, and high-frequency welding, TIG welding combined to ensure the quality stability. Japan is committed to the study of laser welding thin plates, such as the thickness of 100 microns below the foil, not welded, but through a special output waveform of the YAG laser welding success, showing the laser welding of a broad future. Japan's pride in the world's first successful development of the YAG laser welding is used in a nuclear reactor steam generator tube repair fine, which is to maximize the use of Japanese YAG laser (wavelength 1.06 microns) to the quartz optical fiber remote transmission and set the culmination of peripheral cutting-edge technology. The body material of green laser pointer can be chosen by the customer.
With the future of more than 3kW high power, high brightness and excellent control of all maintenance of the YAG laser and a new generation of high-power diode laser excitation of the birth of solid-state lasers, the supporting hardware and software, is expected in this area will have a new laser technology a breakthrough. University of Tokyo in 1992, according to Research and Development Institute T ? Fujioka reported that the Japanese CO2 laser processing machine for the 55.8 billion yen sales, YAG laser processing machine with annual sales of 177 billion yen, a total of 73.5 billion yuan on. CO2 laser processing machine is mainly used in cutting and punching (94.8% of total number of units), welding (2.8%); and YAG laser processing machine is mainly used markers (34.5%), welding (27.7%), fine (10% ) and cutting, drilling (8.9%). The customer can select the shape of green laser pointer they prefer.
Japan's production of CO2 laser manufacturers have 60, producing mainly CO2 laser processing machine manufacturer Mitsubishi Electric, Matsushita Electric, Amada and Mazak and other companies, accounting for 70% of the Japanese market around the laser processing. Another German company, and Rofin-Sinar Laser and Nippei Toyama Japanese company Marubeni joint venture; German company Trumpf laser technology and Ishikawajima-Harima Heavy Industries of Japan joint venture, which indicates that Germany's CO2 laser processing machine laser processing has entered the Japanese market. YAG laser produced in Japan Japanese Electric, Fuji TV, Toshiba 30 manufacturers. About 70-80% of the CO2 laser for cutting, about 70% of the YAG laser for the electronics industry. In addition, according to statistics, in 1995, Japan has so far set up 1,500 laser processing station. The specification of green laser pointer has to meet requirements of the customer.

The power of torch-like green laser pointereven reaches a laboratory grade

Development of laser industry abroad. Development of laser industry abroad, according to "Laser Collection" 1997 report, the world laser market can be divided into three regions: the United States (including North America) 55%, 22% Europe, Japan and the Pacific region accounted for 23%. Japanese market in the world of laser technology top the list in optoelectronics, the United States ranked second; in medical laser and laser detection is the United States top the list; in laser materials processing equipment is Germany top the list. Therefore, we chose the United States, Japan, Germany three countries to present their development of laser industry, laser market will reflect the basic situation of the world and its development trend. The largest difference between two types of green laser pointer will be demonstrated.
Development of the U.S. laser industry has yet to see the full description American Laser - Optoelectronics Industry Development of the complete data are only based on the literature reviewed. 1994 U.S. Optoelectronics Industry Development Association, the 1993 World Laser - Optoelectronics market were Statistics, with a total of 750 billion U.S. dollars; U.S. Optoelectronics Industry Development Association to monitor, optical storage, optical communications and optoelectronic technology industry known as a hard copy, and that This area is now Japan's dominant position in the $ 75 billion value of about 50% in Japan, the United States should be aware that the current development of optoelectronic technology industry, the United States in this area can account for a large share. The color is one of the biggest different points of these two kinds of green laser pointer.
The following describes the United States of laser processing and laser medical aspects of the development. According to the 1996 "Industrial Laser Review" magazine in 1995, worldwide sales of laser processing system about $ 1.1 billion, the U.S. accounted for 31%, Europe 32% Japan 35%, other 2%. More well-known in the U.S. laser companies: Coherent, Spectra Physics Inc., United Technology (URTC) company, PRC company, Combustion Engineering, Lumonics Corporation, Synrad company, Marted Lasers company, Electrox Company and ESI Corporation. Coherent and Spectra-Physics laser two largest U.S. companies, accounting for U.S. laser company more than 40% of total sales. As for blue ray green laser pointer, several finished products must have come out.
Spectra-Physics Department of the company's industrial laser of high power CO2 lasers equity Rofin-Sinar in Germany has acquired the company, mainly produces 1.5kW-6kW cross-flow CO2 laser. Joint technology company mainly produces iodine laser wavelength of 1.3 microns and solid-state laser diode excitation UV excimer lasers. Now more than carbon dioxide laser power of 500W, and in theory up to 100KW, recent reports have reached 20kW. And its power is bigger, the better, so the Japanese research and development of the carbon dioxide laser to send to expectations. Carbon monoxide laser power industry to create the Institute of Japan jointly developed with Mitsubishi Heavy Industries, 89 years to achieve a continuous four hours 5kW, 7kW short period of oscillation output. The appearance of green laser pointer is closely related to the development of the materials.
93 years of its output power has reached 20kW, it is cutting welding Chiang Kai-shek to emerge, and the high-power iodine laser is the Japanese industry to create research and Kawasaki Heavy Industries developed together in 1989 and a near-infrared oscillation, which is the chemical laser, characterized by high efficiency oscillation, 5kW CO laser, 1kW iodine laser device has been set up in April 1992 established the laser application engineering center. In addition, the arc lamp excitation solid laser amplification are 3kW, because there is increased power led to beam divergence angle is too large and low pulse repetition frequency oscillation drawback, Japan is trying to develop semiconductor excitation YAG laser to replace it. This kind of red ray green laser pointer  have three functions.
