我们报道了一个2.09 μ m的Ho:YAG振荡器，在1.9 μ m的频率下被一个二极管泵浦的Tm:YLF激光器共振泵浦的>50-mJ调q能量输出。我们证明了在输出能量为30 mJ时，q开关到正常模式的提取效率为100%，在输出能量为50 mJ时，提取效率超过64%。在50兆焦耳（60赫兹）的输出下工作，从钬振荡器获得了14 ns的脉冲宽度，这相当于3.6 MW的峰值功率。在50兆焦耳的输出水平，光束传播系数M-2类似于1.2实现。(C) 2003年美国光学学会。
We report >50-mJ Q-switched energy output from a 2.09-mum Ho:YAG oscillator, resonantly pumped at 1.9-mum by a diode-pumped Tm:YLF laser. We demonstrate a Q-switched-to-normal-mode extraction efficiency of 100% at an output energy of 30 mJ and over 64% at the 50-mJ output level. Operating at 50 mJ (60 Hz) of output, a pulse width of 14 ns is achieved from the holmium oscillator, which corresponds to similar to3.6 MW of peak power. At the 50-mJ output level, a beam-propagation factor M-2 similar to 1.2 is achieved. (C) 2003 Optical Society of America.
