摘要

摘要: 利用1.06 m光泵浦周期极化钽酸锂（PPLT）晶体获得1.54 m激光。采用内腔式光参量振荡结构，利用V型腔优化谐振腔参数，分析了OPO晶体内光斑大小随激光工作物质热焦距的变化以及V型腔夹角对光束质量的影响。当泵浦电功率约为100 W时，获得高重复频率10 kHz、脉冲宽度125 ns、平均功率1.9 W的1.54 m激光，电光转换效率约为1.9%。

Abstract: A 1.54 m laser was obtained using periodically poled lithium tantalate (PPLT) crystal pumped by 1.06 m laser. Intracavity optical parametric oscillator(OPO) was adopted and parameters of resonant cavity were optimized by using V-type cavity. The change of the beam spot along with the thermal focus length of gain medium and the impact of the angle of V-type cavity on beam quality were analyzed. As the input electric power was about 100 W, the 1.54 m laser with the repetition rate of 10 kHz, pulsewidth of 125 ns and average power of 1.9 W was acquired, and the electro-optical efficiency of 1.9% was achieved.
