© Published under licence by IOP Publishing Ltd. 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.
