摘要
A single-longitudinal-mode(SLM)Tm:YAG ceramic laser under room temperature conditions using double Fabry-Pérot etalons is investigated.The maximum single-frequency output power is 318 mW with a slope efficiency of 12.6%.The wavelength tuning range from 2005 nm to 2029 nm is achieved by tuning the obliquity of a 0.1-mm-thick etalon.The single frequency laser has a beam quality of M^(2)=1.3 at the maximum single-frequency output power.The result is reported for the first time to the best of our knowledge.This SLM Tm:YAG ceramic laser can replace the Tm:YAG single crystal laser to be used as the seed laser for LIDAR laser systems.
