We reported a high-energy, high-pulse-repetition-frequency Ho:YAG master oscillator and power amplifier (MOPA), which was resonantly dual-end pumped by Tm:YLF lasers at room temperature. At a pulse repetition frequency of 1 kHz, the Ho:YAG MOPA laser system produced a maximum pulse energy of 110.4 mJ with a 28 ns pulse width, corresponding to a peak power of approximately 3.94 MW. The output wavelength of the Ho:YAG MOPA laser system was 2090.9 nm. In addition, a beam quality factor M of about 1.7 was achieved at maximum output level.
我们报道了一种高能量、高脉冲重复频率的钬钇铝石榴石主振荡功率放大器（MOPA），它在室温下由掺铥钇锂氟化物（Tm:YLF）激光器进行共振双端泵浦。在1千赫兹的脉冲重复频率下，钬钇铝石榴石MOPA激光系统产生了最大脉冲能量为110.4毫焦、脉冲宽度为28纳秒的激光，对应的峰值功率约为3.94兆瓦。钬钇铝石榴石MOPA激光系统的输出波长为2090.9纳米。此外，在最大输出水平下实现了约1.7的光束质量因子M。
