The aim of this work is growth of LiCaAlF6:Ce3+ (Ce:LiCAF) crystals by Bridgman technique and study of spectroscopic and laser characteristics in UV spectral range. We report on growth of LiCaAlF6:Ce3+ (1.2 at.% in the melt) crystals with refractive index inhomogeneity not worse than Delta n = 1.2 * 10(-5). The maximum absorption coefficient of Ce3+ ions appeared to be up to 7 cm(-1) and maximum of slope efficiency of laser action as high as 47% in synthesized crystals was achieved.
