摘　　要：在带抗共振环 (Anti resonantRing ,ARR)的非稳腔Nd∶YAG激光器中 ,采用Cr4+ ∶YAG作为被动调 Q 元件 ,获得单脉冲能量 >85mJ,脉宽 40ns和能量起伏 0 4%的高能量、高稳定调Q激光脉冲。同时对平 凸非稳腔和平 平介稳腔进行实验比较 ,并对腔型和实验结果进行了初步分析。By using Cr4+: YAG as a saturable absorber, a high-energy and high stability Q-switched pulse with a single pulse energy of more than 85 mJ, a pulse-width of 40 ns and an energy fluctuation of 0.4% was obtained in an unstable resonator Nd:YAG laser with an anti-resonant ring (ARR) structure. The experiments on plane-convex unstable resonator and plane-plane critical resonator were tested for comparison and the results were analyzed.
