摘　　要：根据ABCD传输矩阵理论,对激光二极管侧泵的Nd∶YAG/KTP腔内倍频固体激光器Z型谐振腔进行了理论分析,采用Matlab对腔参数进行了理论计算。通过理论计算,选择适当腔参数进行了实验研究,当重复频率为9kHz,输入电功率302.5W时,获得了17.27W绿光输出,输出不稳定性小于0.9%,电光转化效率为5.7%,光束质量因子Mx2=3.351,My2=3.759,发散角为0.68mrad。According to ABCD transmission matrix theory, A Z-type resonator used for laser di- ode （LD） side-pumped intracavity frequency-doubled Nd： YAG /KTP laser was analyzed and calculated by software Matlab. We selected a set of proper cavity parameters, at 9kHz repeti- tion frequency and 302.5W input electrical power, a 17.27W green laser was obtained with an electrical-optical conversion efficiency of 5.7% and divergence angle of 0. 68mrad, the beam quality was M22/x=3. 351, M2/y=3. 759 ,output instability was less than 0.9%.
