摘要

据我们所知，这是首次展示由 888 nm 激光二极管直接泵浦的 2.1 μm Ho:YAG 激光器。研究了连续波和无源 Q 开关 Ho:YAG 激光器在不同输出耦合器透射率下的输出性能。连续波工作时，吸收泵浦功率为 3.7 W，最大输出功率为 396 mW，斜率效率为 22.6%。在被动 Q 开关操作中，吸收泵功率为 3.7 W 时的最大平均输出功率为 103.2 mW，脉冲宽度为 62.9 ns，重复频率为 1.105 kHz。实验结果表明，888 nm 激光二极管是在 Ho:YAG 晶体中实现 2.1 μm 激光输出的理想泵浦源。

888 nm laser diode end-pumped continuous wave and passively Q-switched Ho:YAG laser

A 2.1 μm Ho:YAG laser directly pumped by an 888 nm laser diode was demonstrated for the first time, to the best of our knowledge. The output performances of continuous wave and passively Q-switched Ho:YAG laser were investigated at the different output coupler transmittances. For the continuous wave operation, the maximum output power of 396 mW was obtained at the absorbed pump power of 3.7 W, corresponding to the slope efficiency of 22.6 %. For the passively Q-switching operation, the maximum average output power was 103.2 mW at the absorbed pump power of 3.7 W, with a pulse width of 62.9 ns and a repetition frequency of 1.105 kHz. The experiment results show that the 888 nm laser diode is a promising pump source to achieve 2.1 μm laser output in Ho:YAG crystal.
