摘　　要：针对Nd∶YVO4晶体热传导各向异性的特点,在泵浦光为高斯光束、泵浦尺寸小于通光面的情况下,求解晶体热传导方程,得到晶体中各点的精确温度,从而分析LD端面泵浦固体激光器的热效应。在理论分析的基础上,优化腔形,设计了V形折叠腔Nd∶YVO4/KTP腔内倍频连续绿光激光器,在泵浦功率为15W时,1064nm和532nm激光输出功率分别为7.42W和4W,光-光转换效率为49.5%,26.7%。For the case of anisotropic laser crystal Nd：YVO4, Gaussian beam pumping and the pump spot size was less than the end facet size of the crystal ,the temperature distribution in the crystal was obtained and the thermal effect of laser diode end-pumped solid laser was analysed. Based on the result of thermal effect study,a V-cavity CW green laser by intracavity frequency doubling was designed. The output power of 7.42 W at 1064nm and 4W at 532nm were obtained at the pumping power of 15W： The optical-optical conversion efficiencies were up to 49.5% ,26.7%.
