【 摘 要 】

Here we report on UV laser oscillation on colquiriite structure fluoride mixture crystals of Ce3+:LiCaAlF6(Ce:LiCAF) and Ce3+:LiLuYF4(Ce:LiLuYF) active media. We report on 800 ps pulse train lasing form Ce:LiCAF in composite cavity and single pulse lasing of 400 ps duration from Ce:LiLuYF in convenient Fabri-Perrot cavity and discuss conditions of pulse shortening in UV active medium by photodynamic processes.
