Abstract

Abstract In this paper, we report a diode side-pumped injection-seeded single-frequency Tm,Ho:YLF laser, which operated at lasing threshold and emitted at 2051.2 nm. The assistance of Fabry-Pérot (FP) etalons to seed injection via mode selection was investigated. An acouto-optic Q-swiched output of 6.7 mJ was achieved at 5 Hz. A temporal pulse duration of 310 ns with spectral linewidth of 2.0 MHz and frequency stability of 0.8 MHz rms was detected. The beam profile was a high quality Guassian TEM00 mode with M2x/y = ~ 1.15/1.14. The application of this 2 µm laser as light source in the wind detection coherent Lidar system was verified.
