摘　　要：使用最大泵浦功率为600 W的LDA侧面泵浦组件,并采用布儒斯特偏振片以及同时优化全反镜和输出镜透过率两种方法,获得了功率基本相等的1319 nm/1338 nm双波长激光输出。在连续输出时,获得30 W的输出功率,利用声-光Q开关调Q输出,在重复频率为4 kHz时,单脉冲能量为6 mJ,脉冲宽度为237 ns,峰值功率为25 kW。In order to simultaneouly generate the laser output with nearly equal power for dual wavelengths of 1319nm/1338nm in the LDA side pumped Nd：YAG laser,two methods that uses a Brewster′s window and optimizes the transmissions at 1319nm and 1338nm of output mirror and reflection mirror at the same time are adopted.In this experiment,a CW LDA pump module made in China has a side pumping structure,and the highest power of LDA is 600 W.The maximum power of CW dual wavelength output is 30 W,and when the A-O Q-switch is operated at 4 kHz,the highest dual wavelength pulse energy is 6 mJ,with the 237 ns pulse width and 25 kW peak power.
