本文报道了一种接近室温的激光二极管端面泵浦连续可调谐单频Tm， Ho:LLF激光器。当传输率为5%时，在2064.4 nm处使用两个未涂覆的标准子可获得最大单频输出功率221 mW。单频Tm， Ho:LLF激光器工作在基频横模上，M2因子为1.13，仅对1 mm厚的标准子进行角度调谐即可在1.5 GHz附近连续调谐输出频率。此外，还研究了输出耦合器透射率对激光器性能的影响。单频激光器可作为相干多普勒激光雷达和差分吸收激光雷达系统的种子激光器。
We report on a laser diode-end-pumped continuously tunable single frequency Tm, Ho:LLF laser near room temperature. For transmission of 5%, the maximum single frequency output power of 221 mW at 2064.4 nm was obtained by using two uncoated etalons. The single frequency Tm, Ho:LLF laser operated on the fundamental transverse mode with an M2 factor of 1.13, and the output frequency could be tuned continuously near 1.5 GHz by angle tuning only of the 1 mm thick etalon. Furthermore, the influence of output coupler transmission on the laser performance was also investigated. The single frequency laser can be used as a seed laser for coherent Doppler lidar and differential absorption lidar systems.
