摘要
报道了蓝光激光二极管(LD)(中心波长约为444 nm)单端纵向抽运掺镨氟化钇锂(Pr3+:YLF)的红光(640 nm)和绿光(522 nm)激光器。用单个棱镜作为抽运光束整形器,实验中红光最高输出功率为308.5 mW,其相应的抽运阈值功率为46 mW,斜率效率为47.5%;绿光这三个指标的值相应分别为193.4 mW、162.3 mW和37.1%。结果表明抽运光的整形提升了红、绿光的输出特性。
Abstract
Red (640 nm) and green (522 nm) lasers with Pr3+:YLF pumped by a blue laser diode emitting at about 444 nm in the longitudinal direction are reported. On the basis of the beam reshaping of the pump spot by a prism, the maximum output power, absorbed threshold pump power and slope efficiency of the red laser are 308.5 mW, 46 mW and 47.5%, respectively. The three corresponding parameter values for green laser are 193.4 mW, 162.3 mW and 37.1%, respectively. The results show that the shaped pump beam is beneficial to improve the output characteristics of these two visible laser emissions.
