All-solid-state blue laser pumped Pr:KY_3F_(10)-BBO ultraviolet laser at 305 nm

摘要

An all-solid-state blue laser pumped Pr:KY_3F_(10) (Pr:KYF) laser at 610 nm has been demonstrated. With an incident pump power of 2.6 W, the maximum output power was 213 mW. Moreover, intracavity second-harmonic generation (SHG) has also been achieved with a maximum ultraviolet power of 11 mW by using a β-BaB_2O_4 (BBO) nonlinear crystal. To the best of our knowledge, this is the first report on continuous-wave ultraviolet generation by intracavity frequency doubling Pr:KYF laser.
