摘　　要：报道了蓝光激光二极管(LD)(中心波长约为444nm)单端纵向抽运掺镨氟化钇锂(Pr3+:YLF)的红光(640nm)和绿光(522nm)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308.5mW,其相应的抽运阈值功率为46mW,斜率效率为47.5%;绿光这三个指标的值相应分别为193.4mW、162.3mW和37.1%。结果表明抽运光的整形提升了红、绿光的输出特性。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 roW, 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.
