In this Letter, a high-power diode-side-pumped Nd:YAG laser emitting at 1338 nm is described. The output characteristics of the laser using the different output couplers for both the cw mode and the Q-switched mode have been studied. With a pumping power of 555 W, the average output power decreases from 70 W at 50 kHz to 55 W (slope efficiency 21.2%, optical conversion efficiency 10%) at 5 kHz. The highest peak power is up to 73 kW with the pulse duration of 150 ns at the repetition rate of 5 kHz. When operated in cw mode, the output power of 100.5 W was achieved, corresponding with the optical slope efficiency of 36%.
在这封信中，描述了一种发射波长为1338 nm的高功率二极管侧面泵浦Nd:YAG激光器。研究了该激光器在连续波模式和调Q模式下使用不同输出耦合器时的输出特性。泵浦功率为555 W时，平均输出功率从50 kHz时的70 W降至5 kHz时的55 W（斜率效率21.2%，光转换效率10%）。在5 kHz重复频率下，脉冲持续时间为150 ns时，最高峰值功率高达73 kW。在连续波模式下运行时，实现了100.5 W的输出功率，对应的光斜率效率为36%。
