We report on diode-pumped continuous-wave Pr-doped yttrium lithium fluoride[Pr∶YLF]laser and its frequency doubling to 320 nm.The maximum output power of the 640 nm fundamental wave reached 3.44 W with a slope efficiency of about 48.3％.Using a type-Ⅰ phase-matched lithium triborate[LBO]crystal as a frequency doubler,we have achieved 320 nm ultraviolet radiation with a maximum output power of 1.01 W,which is the highest power ever reported under diode pumping,to the best of our knowledge.

Spectroscopic and laser properties of Er3+,Pr3+ co-doped LiYF4 crystal
In this paper,the absorption and fluorescence spectra of Er3+,Pr3+ co-doped LiYF4[Er,Pr∶YLF]crystal were measured and analyzed.The Pr3+ co-doping was proved to effectively enhance the Er3+ ∶4I11/2 → 4I13/2 mid-infrared transition at the 2.7 μm with 74.1％
