摘　　要：报道了542.7 nm连续输出的全固态倍频绿光激光器。采用三镜折叠腔结构,用20 W激光二极管(LD)抽运掺杂钕原子数分数为0.2%的Nd:YVO4晶体,选择长度为10 mm的Ⅱ类临界相位匹配磷酸氧钛铷(RTP)晶体进行腔内倍频,获得了542.7 nm激光输出。当注入抽运功率为19 W时,倍频绿光激光最大输出达2.4 W,光-光转换效率为13%,绿光激光输出功率稳定度在30 min内优于2.8%,光束质量因子M2=1.22。An all solid-state doubling frequency continuous-wave green laser at 542.7 nm is reported.By using a three-mirror folded cavity resonator and pumping the Nd：YVO4 crystal whose doping Nd3＋ concentration is 0.2%（atom fraction） with a 20 W output power laser diode（LD）,a green laser at 542.7 nm is obtained by reasonably chosing a 10 mm long type Ⅱ critical phase matching RbTi OPO4（RTP） crystal to intra-cavity doubling frequency.When the incedent pump power is 19 W,the maximal output power is 2.4 W,the optical-optical conversion efficiency is up to 13%,the power stability in half an hour is better than ±2.8%,and the M2 factor is 1.22.
