We report the first observation to our knowledge of room-temperature continuous-wave laser operation of a Pr(3+):KY(3)F(10) single crystal at 644.5 nm, pumped by a blue GaN laser diode emitting at 446 nm. With a 2.5% transmission output coupler and a nonoptimized optical cavity, an output power of 39 mW was obtained at 644.5 nm with a laser threshold of 125 mW and a differential slope efficiency of 23%.
据我们所知，我们首次报道了用发射波长为446 nm的蓝色氮化镓激光二极管泵浦的Pr(3+):KY(3)F(10)单晶在室温下实现644.5 nm连续波激光运转。采用2.5%透过率的输出耦合器和未优化的光学腔，在644.5 nm处获得了39 mW的输出功率，激光阈值为125 mW，微分斜率效率为23%。
