摘　　要：对Nd:YAG 946 nm和473 nm激光器特性进行了实验研究。采用二极管端面泵浦平-平腔实验结构,使用键合Nd:YAG晶体作为激光增益介质,在入射泵浦功率31.8 W时,得到最高11 W的连续波946 nm激光输出,光-光转换效率34.6%,斜率效率35.4%,光束质量M2达到7.53,半小时内功率不稳定度小于0.4%。采用I类临界相位匹配LBO晶体对946nm激光进行内腔倍频,获得了0.887 W的连续波473 nm蓝光输出,光-光换转效率5.87%。实验结果表明:所设计的端面泵浦连续激光器具有很强的实用价值。The properties of Nd：YAG 946 nm and 473 nm laser were studied. By using Nd：YAG composite as laser gain medium, 11 W continuous-wave （CW） laser output at 946 nm was obtained under the incident pump power of 31.8 W, corresponding optical efficiency and slope efficiency were 34.6%and 35.4%, respectively. The M2 factor was 7.53 and the power stability was better than 0.4% with 0.5 h. After intra-cavity frequency-doubled by an LBO crystal which was cut for critical type I phase matching, 0.887 W CW output power at 473 nm was obtained, corresponding to an optical efficiency of 5.87%. Experimental results prove that the end pumped CW laser has important practical value.
