New ultraviolet, tunable, solid-state laser medium: Ce/sup 3+/:LiSr/sub 0.8/Ca/sub 0.2/AlF/sub 6/ for high-peak-power amplifier

Ce/sup 3+/:LiSr/sub 0.8/Ca/sub 0.2/AlF/sub 6/ is grown as a new tunable ultraviolet laser medium. Its longer fluorescence lifetime compared with that of Ce/sup 3+/:LiCaAlF/sub 6/ is a potential advantage as an amplification medium. The preliminary laser operation is also confirmed.
