摘　　要：报道了LD端面分别泵浦Nd:YVO4、Nd:GdVO4晶体,腔内类相位匹配KTP倍频的绿光激光器。通过对激光材料热透镜效应的分析,得出优化的谐振腔参数,在泵浦功率为6.1 W时得到的绿光激光器的光-光转化效率分别为15.5%、10.7%。从实验结果中,得到两种激光晶体的一些性能差异,为以后的研究提供一些参考。A laser-diode pumped CW Nd ： YVO4,Nd ： GdVO4 green laser with KTP（type- Ⅰ critical phase matching）is reported. By analyzing and calculating the effect of thermal lens, the optimized parameters are derived from the experiment. The TEM00-mode green laser output power is 0. 947 W and 0. 655 W at 6. 1 W incident pump power, corresponding to an optical conversion of 15.5 %, 10. 7 %. From the result of the experiment, some different performances of two kinds of laser crystals have been found out, these results can offer some references to further researches.
