New all-solid-state tunable UV Ce3+, Yb3+:LiY0.4Lu0.6F4 laser

Here we report laser test results of the new UV solid-state active medium based on a Ce3+, Yb3+:LiY0.4Lu0.6F4 mixed crystal pumped by radiation from Ce:LiCAF laser. The 10-Hz pulse repetition rate Ce3+, Yb3+:LiY0.4Lu0.6F4 laser yielded a maximum output power of 0.25 mJ at 311nm in non-optimized non-selective resonator with a maximal slope efficiency of 13%. Tunability from 304 to 332 nm was achieved in the selective single-prism resonator.
