摘　　要：设计出一种能够较好地补偿激光晶体热效应的激光谐振腔,实现了高稳定LD单端泵浦LBO腔内倍频Nd∶YVO4连续红光激光器.当晶体吸收的泵浦功率为24.56W时,671nm激光功率达到1.203W,光-光转换效率4.9%,激光模式为TEM00模.在输出功率为1.08W时,激光器1h功率不稳定度为0.52%.A laser resonator that can compensate the thermal lensing effect of the laser crystal greatly is designed. Thus a continuous wave laser with high stability at 671 nm by intracavity frequency doubling of a Nd ： YVO4 laser based on the nonlinear crystal I.BO is achieved. The 671 nm laser reaches 1. 203 W when the absorbed pump power is 24.56 W,with TEM00 mode and an optical to optical efficiency of 4.9%. The amplitude noise is 0. 520/00 （rms） in an hour when the output power is at about 1.08 W.
