摘要：

Blue laser diode pumped Pr:YLF solid-state green laser is reported. A 5 mm long Pr:YLF crystal with the doping concentration of 0.5% is used as laser gain material, pumped by a blue laser diode with emitting central wavelength at 444 nm. Continuous-wave green laser output at 522.4 nm is obtained. Input and output characteristics of the lasers are studied with different output couplers. Under an absorbed pump power of about 530 mW, the maximum output power of 90.1 mW is obtained with 1.9% transmission coupler. The slope efficiency is as high as 65.3%.
