Study on the Pr:KYF ultraviolet laser at 305 nm pumped by blue laser

Abstract

An all-solid-state Pr:KY₃F₁₀ (Pr:KYF) laser pumped by blue laser (471 nm) has been demonstrated. With the incident pump power of 2.6 W, the maximum output power at 610 nm is 213 mW. Moreover, the intracavity second-harmonic generation (SHG) is also achieved with the maximum ultraviolet (UV) power at 305 nm of 11 mW by using a β-BaB₂O₄ (BBO) nonlinear crystal.
