[Abstract]:With the rapid development of all-solid-state laser technology, Q-switched technology and nonlinear frequency conversion technology, all-solid-state green laser is more and more widely used in scientific research, laser medical treatment, laser processing, military defense, and laser display and other fields. In the field of laser display, high power red, green and blue three-color all-solid-state laser technology, as the key technology of laser color display, is one of the frontier research topics in the international laser field, and has been paid close attention to by researchers. Laser diode pumped all-solid-state laser (Diode Pump All-Solid State Laser,DPSSL) has the advantages of high efficiency, all-solid-state, stability, long life, simple and compact structure, high power and good beam quality laser output. All-solid-state laser combined with nonlinear optical frequency-doubling technique is the most promising way to obtain all-solid-state green laser (Diode Pump All-Solid State Green Laser,DPSSGL). That is, 1064 nm fundamental frequency light is obtained by laser gain medium pumped by semiconductor laser diode or laser light source array, and 1064nm pulse laser with high peak power is formed by combining Q-switched technology. High power 532nm green light output is achieved by adding nonlinear frequency-doubling crystals (such as KTP,LBO,BBO). Under the background of the national 863 project "study of XXX laser light source", the related theoretical analysis and experimental research on the engineering 100-watt green laser are carried out. Finally, an engineering prototype of a 126W high power all-solid-state green laser with fiber coupling output is developed. The coupling efficiency of the fiber is 90.33.The green light is continuously output for 3 hours. The power fluctuation is less than 鹵1.29. The average power and power stability of the laser operating stably at 532 nm are in line with the technical requirements of the project.
