Tm Pulse Laser Pumped Mid-IR Solid State Laser

介绍了Tm：YAP脉冲激光器泵浦的中红外固体激光器。首先介绍了Tm脉冲激光器,由实验分析,对YAP固体激光器腔型结构进行优化,确定了适合泵浦ZGP OPO的YAP激光器腔型,得到较理想的2μm脉冲激光输出。中红外固体激光器由优化后的Tm：YAP激光器泵浦ZGP光学参量振荡器（OPO）组成,最终得到输出功率达瓦级以上的3~5μm激光。

A Tm：YAP laser pumped Mid-IR solid-state laser is reported.First,the Tm pulse laser is described,the structure of laser cavity is optimized by analyzing the experiment results.Then,the appropriate type of YAP laser cavity of ZnGeP2 OPO pump is confirmed,and obtained 2 μm pulse laser output is ideal.Mid-IR solid state laser is composed of optimized Tm：YAP laser pump optical parametric oscillator（OPO）.Finally,more than Watt-level output power at 3～5 μm is obtained.
