首次展示了由 1.91 µm 激光二极管谐振泵浦的 2.09 µm 注入种子单频 Ho:YAG 激光器。种子激光器是连续波 (CW) Ho:YAG 非平面环形振荡器。注入种子调Q Ho:YAG 激光器获得了 15.15 mJ 的单频输出能量，脉冲重复率为 200 Hz，脉冲宽度为 109 ns。使用外差技术测得脉冲频谱的半宽度为4.19 MHz。单频脉冲中心频率在1 h内的波动为1.52 MHz（均方根（RMS））。
A 2.09 µm injection-seeded single-frequency Ho: YAG laser resonantly pumped by a 1.91 µm laser diode is demonstrated for the first time. The seed laser is a continuous wave (CW) Ho: YAG non-planar ring oscillator. 15.15 mJ single-frequency output energy is obtained from the injection-seeded Q-switched Ho: YAG laser, with a pulse repetition rate of 200 Hz and a pulse width of 109 ns. The half-width of the pulse spectrum is measured to be 4.19 MHz by using the heterodyne technique. The fluctuation of the center frequency of the single-frequency pulses is 1.52 MHz (root mean square (RMS)) in 1 h.
