摘　　要：利用横向泵浦腔体实现氟化钾镁晶体色心室温稳定激光器运行。用氮分子激光泵浦的染料激光为泵浦源 ,单脉冲色心激光输出能量为 0 .2 2 m J,光 -光能量转换效率为 7.3% ,激发阈值为 0 .5 m J。色心激光束发散角为 3.0 mrad,偏振度为 0 .99。色心激光输出波长从 70 3nm至 80 0 nm,中心波长位于 75 5nm。A stable potassium magnesium fluoride color-center laser operated at room temperature using transversely pumped cavity is constructed. The laser is pumped with a pulse day laser pumped by a nitrogen laser. The single pulse output of the laser is 0.22 mJ, the optical-optical conversion efficiency is 7.3%. The excitation threshold is 0.5 mJ. The divergence of the laser beam is 3.0 mrad. The degree of the polarization of the laser is 0.99. The laser output extends 703 nm to 800 nm and peak at 755 nm.
