摘　　要：报道了光纤耦合激光二极管端面抽运Nd∶YAG晶体 ,Ⅰ类临界相位匹配LBO腔内倍频的 4 73nm全固态蓝光激光器。通过对准三能级系统进行分析 ,采用国产普通Nd∶YAG晶体棒作为工作物质。将热效应因素考虑在内 ,设计出对热效应不敏感的短三镜折叠腔 ,通过改善致冷条件 ,在 14W的抽运功率下获得了 1 1WTEM0 0 模连续4 73nm蓝光输出 ,光 光转换效率达 7 9%。阈值仅为 2W。讨论了获得更高输出功率的可能性。A LD pumped Nd∶YAG, LBO (type Ⅰ critical phase matching) intracavity frequency doubled, blue laser at 473 nm is reported in this paper. With the quasi three level model and a ordinary Nd∶YAG rod as gain medium, by using a short three folded cavity resonator that is in sensitive to thermal effect, under the condition of 14 W pump power, high power TEM 00 mode blue laser at 473 nm of 1.1 W is obtained at last, with the light light conversion efficiency up to 7.9%, the threshold value is just 2 W. Moreover, the possibility of improving the power is discussed.
