摘要

A stable wavelength operation Ho∶YAG laser dual-pumped by two orthogonally polarized Tm∶YLF lasers is reported.Under the cw operation mode,a laser output power of 24 W is measured.The corresponding opticaloptical conversion efficiency is 44.75％ and the slope efficiency is 50.12％.Under the Q-switched operation mode,the output maximum average power is 22.8 W at the re-frequency of 6 kHz.The corresponding optical-optical conversion efficiency and slope efficiency are 42.64％ and 48.01％,respectively.The output central wavelength is 2090.73nm,the linewidth is 0.40nm,and the beam quality is M2 ＜ 1.6.Moreover,the shift of the output central wavelength is less than 0.01 nm,and the linewidth shift is also less than 0.01 nm.
