摘　　要：概述了2μm激光器的发展状况及应用背景, 通过对2μm激光两种实现方式的比较,最终采用了可调谐方式间接获得2μm激光的方案。以1.06μm激光为泵浦源,采用二极管泵浦腔内OPO的方案能有效提高泵浦峰值功率密度,有利于实现高重复频率2μm激光输出。利用KTP晶体在特定切割角度下实现波长简并输出,合理设计OPO腔,可以有效提高2μm激光的输出效率。同时进行了激光输出实验,实现了功率11.2 W的2 m波长激光输出。The development and application background of 2 μm laser were summarized. Two schemes to obtain 2 μm laser were compared and the indirect tunable scheme was adopted. After LD pumped intra-eavity KTP OPO being adopted, the pump peak value power density was increased and high repetition frequency of 2 μm laser was implemented easily. With KTP crystal cut under specifically angle and OPO resonator designed reasonably, 2 μm laser output efficiency was improved effectively. 2 μm laser experiment was performed, and 11.2 W of 2 μm laser output was realized.
