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%.
