| 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473nm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1．1W TEM00模连续473nm蓝光输出，光-光转换效率达7．9％。阈值仅为2W。讨沦了获得更高输出功率的可能性。

| Abstract: | 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 TEM00 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. |
