摘要：
This paper demonstrates a single-frequency injection-seeded laser with a Q-switched Ho:YAG laser consisting of two corner cube reflectors. As a seed laser, the Ho:YAG NPRO has an available output power of 1.8 W and operates at 2090.6964 nm. The single-frequency pulse energy obtained in the case of injection-seeded is 6.8 mJ, the pulse width is 166 ns, and the Q-switched Ho:YAG laser operates at a repetition rate of 100 Hz. The Ho:YAG single-pass amplifier scales single-frequency energy from 6.8 mJ to 32.3 mJ. The pulsed spectrum has a half-width of 2.84 MHz. The Ho:YAG amplifier has a beam quality of 1.1 and 1.17 in the x and y axes.
