摘　　要：在带抗共振环 (ARR)的非稳腔 Nd∶ YAG激光器中 ,将调 Q材料 Cr4+ ∶ YAG晶体和L i F∶ F2 色心晶体置于 ARR中心 ,获得调 Q单脉冲能量分别为 86 .1m J和 85 .3m J.这一输出能量远大于相同实验条件下传统的平 -凸非稳腔激光器 ,理论分析很好地解释了实验结果 .The unsteady resonator Nd∶YAG laser is equipped with an antiresonant ring(ARR). Cr 4+ YAG crystal and LiF∶F 2 color center crystal as Q switched materials were placed in the center of the ARR. They obtained the single pulse Q switched output energy of 86.1 mJ and 85.3 mJ respectively, which are much greater than that from conventional plane convex unsteady resonator laser under the same experimental condition. These experimental results are satisfactorily explained by theoretical analysis
