In this paper, we report the experimental realization of a high-repetition-rate single-frequency Ho-doped yttrium aluminum garnet (Ho:YAG) ring laser at 2.09 μm. Single-frequency operation of the ring laser is achieved by injection-seeding with a continuous wave (CW) Ho:YAG non-planar ring oscillator (NPRO) laser. The output energy of the ring laser is 6.24 mJ with a pulse width of 172 ns and a repetition rate of 1 kHz. The beam quality M-factor is measured to be ∼1.3 at the maximum output energy. The half-width of the pulse spectrum is measured to be 2.61 MHz by a heterodyne technique.
在本文中，我们报道了在2.09μm波长下高重复频率单频掺钬钇铝石榴石（Ho:YAG）环形激光器的实验实现。该环形激光器通过用连续波（CW）Ho:YAG非平面环形振荡器（NPRO）激光器进行注入种子实现单频运转。环形激光器的输出能量为6.24mJ，脉冲宽度为172ns，重复频率为1kHz。在最大输出能量下，测量得到光束质量M因子约为1.3。通过外差技术测量得到脉冲光谱的半高宽为2.61MHz。
