Single-frequency operation in the range of 2102.45-2102.54 nm and 2130.72-2130.82 nm is demonstrated from a Tm,Ho:YAP laser at room temperature. To our knowledge, this is the first time a room temperature single-frequency Tm,Ho:YAP laser of up to 72.6 mW at 2102.5 nm with Fabry-Perot etalons has been obtained. Regulating the elevation angle of the two etalons, 42.0 mW at 2130.8 nm was obtained. The single-longitudinal-mode laser can be used as a seed laser for coherent wind measurements and differential absorption lidar systems.
从 Tm，Ho：YAP 室温激光器中演示了在 2102.45-2102.54nm 和 2130.72-2130.82nm 范围内的单频操作。据我们所知，这是首次使用法布里-珀罗标准具获得高达 72.6mW 的 2102.5nm 室温单频 Tm，Ho：YAP 激光器。调节两个标准具的仰角，可获得 2130.8nm 的 42.0mW。单纵模激光器可用作相干风测量和差分吸收激光雷达系统的种子激光器。
