Ensure the good working status of green laser pointer

Two features of the third addition to the previous two groups, there is a feature monochrome laser, nature can not find the frequency of "pure" light, the various frequencies of light are always mixed together. However, due to the interference effect of the laser optical resonator, only those who meet the cavity resonance frequency to form a laser output, not satisfied with the frequency of the resonance conditions, destructive interference in the resonant cavity, the laser frequency single, monochrome very good to get the helium-neon gas laser, it produces a range of wavelengths less than ten billion one micron, can be regarded as a single deviation wavelength, is very pure monochromatic light. The truck full of green laser pointer is near the gate of the company.
Information collected by the fourth group, our group talked about, in addition to the previous three groups, as well as that the directionality of the laser, a good flashlight or searchlight condenser looks they shot the beam is straight, but in twelve kilometers later, the light would diverge into a great one, the brightness is significantly reduced, while the laser shines on this distance on the basic divergence, the laser is the most consistent direction, the highest concentration of light. Division: the first group of students to read from the perspective of the laser characteristics collected a lot of information, better, although some materials that we can not completely understood, but later we still have a lot of learning opportunities to further understand the following, we again the data exchange of laser applications. The led flash light company asks the staff members to wear the labor protection appliance during the manufacture process.
Laser with high energy, so it is a precision machining in particular is an indispensable tool of microelectronics industrial processing of metal using laser drilling, cutting, welding, hardening, laser instead of a mechanical tool and burin direct processing of large-scale and micro-components unmatched by ordinary machining characteristics. Use of hard materials, it can fight diameter of 0.1 mm to a few microns holes. Laser drilling from the processing of the material hardness and brittleness, and the drilling speed is exceptionally fast, can be a few thousandths of a second or even millions of The surface is very whole Qi Guangjie holes drilled within the nanosecond laser rapid automatic molding technology, you can control the laser beam to the material layer by layer "sintering" the formation of physical parts or molds, models. The ventilated condition of the warehouse of green laser pointer can ensure the good working status of green laser pointer .
It can be quickly made into sophisticated mechanical parts or irregular pattern. China has developed laser rapid automatic molding machine, indicates that China has mastered this new technology, and quick access to localization, commercialization stage. Widely used laser in agricultural production with laser irradiation crop seeds, can induce genetic variation, to shorten the germination time bringing out the seedling growth of fast growing good, thick and uniform neatly, to improve the crop growth and performance, to increase production. laser technology into fruit Caipei, can improve the quality of the fruit to improve fruit production. laser livestock, poultry, fish, can promote the growth and development. The new building of the warehouse of green laser pointer has been put into service.
The Laser in clinical medicine "laser knife" can be effective in local heating solidified blood vessels, less bleeding, and "knife" does not and organization contacts, without disinfection, laser knife is very sharp, cutting the soft tissue and hard-organization are the same shortcuts, but also can be applied laser irradiation on acupuncture points, to the point of input energy, painless, sterilization, fast and secure. The laser has important applications in the information industry. In optical fiber communication, laser for communications carrier as the carrier of high-speed transmission of information and it is a high-speed processing of information carrier, the optical computer has incomparable advantages of the ordinary computer. laser communication system restore.
