9.3 W continuous-wave intracavity frequency-doubled Pr:YLF laser at 320 nm pumped by fiber-coupled GaN blue laser diodes

We report a continuous ultraviolet laser operating at 319.804 nm by intracavity frequency-doubled Pr:YLF laser pumped by fiber-coupled GaN blue laser diodes. The pump source is a fiber coupled LD module with the maximum output power of approximately 40 W which consists of eight GaN blue LDs with a maximum single-emitter output power of 5 W. Using a 18 mm long Pr:YLF crystal and a 10 mm long LBO crystal as nonlinear frequency doubler, coherent radiation with an output power of 9.3 W was achieved with respect to the total pump power, leading to a efficiency of 24.8% from pump power to output power.
