Abstract

Continuous-wave 457 blue laser emission at powers as high as 4.6 W is achieved by using a fiber-coupled laser diode array with a power of 30 W to pump 0.1 at. % low-doped bulk Nd:YVO4 crystal, with intracavity frequency doubling in a 15 mm long type I critical phase-matched LiB3O5 (LBO) crystal in a compact three-fold cavity with a length of less than 100 mm. The optical-optical conversion efficiency is greater than 15.3%, and the stability of the output power is better than 3% for an hour.

摘要

通过使用功率为30 W的光纤耦合激光二极管阵列泵浦0.1原子百分比的低掺杂块状Nd:YVO4晶体，在长度小于100 mm的紧凑型三折叠腔中，于15 mm长的I型临界相位匹配的LiB3O5（LBO）晶体中进行腔内倍频，实现了高达4.6 W功率的连续波457蓝光激光发射。光-光转换效率大于15.3%，输出功率在一小时内的稳定性优于3%。
