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.
