The application of green laser is described briefly

All-solid-state lasers are developing in the direction of multi-wavelength, among which LD pumped all-solid-state green lasers are developing rapidly and are widely used in various fields.
For medical applications
Because the human eye is most sensitive to green light, pulsed lasers with a wavelength of 532ITm can be used in eye surgery. The pulsed green light can also be used to treat vascular diseases. A 532nm Q-switched pulse laser with output power of 3W was designed and manufactured to treat stroke. Pulsed green laser because of its high power, so the action time on the skin is relatively short, so the laser will not produce non-selective heating of the skin tissue around the target tissue, so as not to cause thermal damage, reducing the risk of surgery.
Application in the field of color display
Compared with other display light sources, laser display technology has a wide gamut, high color purity, flexible display screen size, no harmful electromagnetic ray radiation and other unique advantages, can be used in home theater, digital theater, large screen projection, public information screen and teaching demonstration, virtual reality simulation and many other fields, become the home and outdoor future preferred video display equipment. The image displayed by laser is richer and more colorful than the existing color TV, can reflect the true color of nature, and even display virtual color, so the high-power three-color all-solid-state laser as a key technology of laser color display, has become a major development direction of the current international laser field research.
Applications in laser precision machining
Green laser due to its high brightness, small focus spot, short action time, small heat affected zone, workpiece will not cause large deformation due to processing and other advantages, can be processed for some high hardness, brittle materials, in precision machining shows its unique advantages. In addition, lasers are also widely used in the electronics industry and can be used to adjust the resistance value of micro-resistors. With the improvement of laser performance and the emergence of new lasers, the application of laser in VLSI has become a key technology that can not be replaced by many other processes, showing an encouraging prospect for the development of VLSI.
As a laser pump source
Ultraviolet laser and deep ultraviolet laser have a wide range of applications in military, industry, medicine, printing, etc. The use of green light as a pump source is the most effective and most extensive method to produce ultraviolet and deep ultraviolet laser. LD pumped solid state laser can be used as a femtosecond laser pumping source, such as using a green laser as a pumping source, pumping Ti:Al2O crystal to produce femtosecond pulses. In addition, the green laser can also be used as the pump source of all solid continuous green laser pumped by parametric oscillator LD. In addition, all-solid green lasers are also widely used in optical storage, information processing, laser spectroscopy and holography, coherent communication, laser entertainment, liDAR, interferometry, optical data storage, military industry and other fields. Therefore, all solid green laser has very important scientific research value and broad application prospect.
