Abstract

报道了一种激光二极管（LD）端面连续抽运的高重频、高光光效率电光调Q Nd：YVO4激光器。采用RbTiOPO4（RTP）晶体对作为调Q元件，通过减小热效应和模式匹配技术，实现了高效率的高重频窄脉宽1 064 nm脉冲激光输出。一方面采用低吸收系数的914 nm波长抽运Nd：YVO4晶体，使晶体内热分布均匀，从而获得高量子效率的同时减小了热效应影响。另一方面通过优化泵浦光斑半径，实现泵浦光和振荡光好的模式匹配。在重频200 kHz时，获得了最高输出功率16 W，脉宽9 ns，单脉冲能量80 J，光束质量M21.2的稳定脉冲激光，泵浦吸收功率31 W，对应的光光转化效率为51.6%。据笔者所知，这是RTP电光调Q实现的最高效率的脉冲激光器。
