报道了蓝光激光二极管抽运的掺镨氟化钇锂(Pr:YLF)固体绿光激光器。采用长度5mm、掺杂离子数分数为0.5%的Pr:YLF晶体作为激光增益介质,在中心波长444nm的蓝光激光二极管抽运下,获得波长522.4nm的连续绿光激光输出。应用不同透射率的输出耦合镜研究了激光器的输入输出特性。在吸收抽运光功率530mW,输出镜透射率为1.9%时获得最大输出功率为90.1mW,斜率效率达到65.3%。
Reported a blue laser diode pumped p-doped lithium yttrium fluoride lithium (Pr: YLF) solid green laser. A continuous green laser with a wavelength of 522.4nm was obtained under the condition of a blue laser diode with a center wavelength of 444nm using Pr: YLF crystal with a length of 5mm and a doping fraction of 0.5% as the laser gain medium. The output coupling mirror with different transmittance was used to study the input and output characteristics of the laser. The maximum output power of 90.1 mW and the slope efficiency of 65.3% were obtained when the pump power was absorbed at 530 mW and the output mirror transmittance was 1.9%.
