Tunable solid-state laser action in Ce3+:LiSrAlF6

Continuously tunable UV laser operation of cerium-doped LiSrAlF/sub 6/ (Ce/sup 3+/:LiSAF) between 285 and 297 nm is demonstrated. At the peak operating wavelength of 290 nm, output energies of 1.3 mJ with slope efficiencies of 17% have been obtained.
