Abstract
This paper presented a single-frequency Ho:YAP ring laser, whose wavelength was variable and the pump source was the Tm fiber laser. Through rotating the Faraday rotator and the half-wave plate, we achieved 307 mW single-frequency Ho:YAP laser and the slope efficiency was 21.5% and the wavelength was 2118.45 nm. The M2 factor was about 1.1. In addition, the single-frequency laser 2117.05–2119.25 nm was realized through rotating the Fabry–Perot etalon with a bandwidth of 150 GHz.
