Application of three laser technologies
In the field of laser processing, there are three main forms of application of laser technology, namely high power laser pointer marking, laser cutting, and laser welding. The laser is composed of a gain medium, a pump source, and an optical resonant cavity. The gain medium is the source of photon generation. By absorbing the energy generated by the pump source, the gain medium transitions from the ground state to the excited state. Since the excited state is an unstable state, at this time, the gain medium will release energy to return to the steady state of the ground state. Divided by working mode, lasers can be divided into continuous lasers and pulsed lasers. CW lasers can continuously output for a long period of time, work stably, and have high thermal effects. Pulsed lasers output in pulsed form, and the main features are high peak power and small thermal effects. Laser processing uses a high-power density laser beam to irradiate the workpiece to melt and vaporize the material for special processing such as perforation, cutting and welding. Early laser processing was mostly used for drilling small holes and micro-welding due to its low power.

By the 1970s, with the emergence of high-power carbon dioxide lasers, high-repetition rate yttrium aluminum garnet lasers, and in-depth research on green laser pointer processing mechanisms and processes, laser processing technology has made great progress, and the scope of use has been expanded. As a new light source invented in the last century, laser has the characteristics of good directionality, high brightness, good monochromaticity and high energy density. It has been widely used in industrial production, communications, information processing, medical and health, military, cultural education, and scientific research. etc. According to statistics, from high-end optical fibers to common barcode scanners, the market value of laser-related products and services is as high as trillions of dollars each year. my country's laser products are mainly used in industrial processing, occupying more than 40% of the market space.
