摘要

我们报告了一种使用纯砷化镓作为可饱和吸收体的无源 Q 开关 2 μm Ho :YAG 陶瓷激光器。在 1.28 W 的吸收泵浦功率下，测得的最高脉冲重复率、最短脉宽、最大单脉冲能量和最高峰值功率分别为 295 kHz、83 ns、1.49 μJ 和 17.95 W。据我们所知，这是第一台采用纯砷化镓吸收体的 2 μm 被动 Q 开关激光器，三光子吸收被认为在可饱和吸收过程中发挥了重要作用。

Passively Q-Switched Ho :YAG Ceramic Laser with a GaAs Saturable Absorber

We report on a passively Q-switched 2 μm Ho :YAG ceramic laser, using pure GaAs as a saturable absorber. At an absorbed pump power of 1.28 W, the highest pulse repetition rate, shortest pulse width, largest single pulse energy, and highest peak power are measured to be 295 kHz, 83 ns, 1.49 μJ and 17.95 W, respectively. To the best of our knowledge, this is the first 2 μm passively Q-switched laser with a pure GaAs absorber, the three-photon absorption is believed to play an important role in the saturable absorption process.
