Green light has spread throughout the past few years, and its technology is changing with each passing day. It has made great developments in China. Although it has been widely spread abroad, it is still very narrow in the domestic market. The following uvc chip manufacturer introduces.
The green light module is composed of a laser crystal and a nonlinear crystal. In the laser resonator, LD pump light with a wavelength of 808nm is used to generate 1064nm laser light through the gain effect of the laser crystal, and then through the frequency doubling effect of the nonlinear crystal. Can emit 532nm green laser. The green light module is similar to the integrated circuit in the electronic component, has the characteristics of modularization and integration, and can be mass-produced to reduce costs.
The green light module adopts the more popular photoresist process in the production method. Compared with the adhesive bonding: there is no optical vacancy on the bonding surface, the green light output power is high, the output method is good, the light spot flicker is low, and the continuous stable output can be achieved; Under the condition of 20OmW diode pumping, the crystal standard is 0.8X0.8X2, and its output green light power is generally 5-10mW. Other conversion powers are closely related to the quality of laser diodes and crystals. The current market is extremely advanced technology and materials. The conversion power can be as high as 35% or more.
The green light module is extremely convenient when making laser resonators, so it has become the core component of the laser diode pumped all-solid-state laser (DPSSL). DPSSL has the advantages of compact structure, high energy conversion power, high power, good beam quality, long life, and convenient use. It is one of the primary devices for generating low-power green lasers. It is used in color display, laser entertainment, laser medical treatment, and underwater communications. There are important applications in such areas.
