摘　　要：文章利用腔内光学元件对傍轴光线的ABCD变换矩阵，分析了热透镜效应对U型谐振腔腔型稳定性的影响。在此基础上，对连续激光二极管阵列侧面泵浦的声光调QNd：YAG固体激光器进行了试验研究，使用熔石英声光Q开关，在泵浦电流I1=18A，I2=20A时，实现重复频率10kHz，平均功率135W，脉冲宽度55ns绿光输出，光光转换效率14．8％，功率不稳定度小于3％。In this paper, the impact of thermal lens effect on U-shaped cavity stability was analyzed by using ABCD matrix formalism. A Q-switched diode-side-pumped Nd：yAG laser was researched on the basis of the proposed method. By using fused quartz crystal for AO Q-switching, under the pumping currents of I1 = 18 A and I2 --20 A, an average green power of 135 W was generated at 10 kHz repetition rate and 55ns pulse-width, leading to 14.8% of optical-optical conversion efficiency and power instability within ＋ 3%.
