激光雷达、激光先进制造、科学研究等方面对100 Hz高光束质量高能激光有着重要的需求。国际上超过5 J的100 Hz高光束质量全固态激光器主要是采用大尺寸板条状Nd∶YAG晶体,我们采用棒状激光晶体,实现了重复率为106.7 Hz,光束质量M2为3.95,脉冲宽度为244μs,单脉冲能量为5.25 J的
Laser radar, laser advanced manufacturing, scientific research and other aspects of the 100 Hz high beam quality high-energy laser has an important demand. Internationally, the 100 Hz high beam quality all-solid-state laser with a frequency of more than 5 J mainly uses large-sized lath-shaped Nd: YAG crystals. We use rod laser crystals to achieve a repetition rate of 106.7 Hz, a beam quality of M2 of 3.95 and a pulse width of 244μs, single pulse energy of 5.25 J
