Two-inch size LiCaAlF6 (LiCAF) single crystals doped with Mg2+ and Ba2+ were successfully grown by the Czochralski technique. Optical absorption measurements in the UV/VIS spectral regions following X-ray irradiation (radiation-induced absorption) were performed in order to investigate the radiation damage of the crystals. It is found that the amplitude of the F-absorption band is suppressed more than a factor of 3 by Mg doping, while in the case of Ba-doped LiCAF, no significant variation is observed. For Mg-doped crystals, the optimum doping concentration is about 0.2mol% of Mg2+. The crystallinity was studied using X-ray rocking curve analysis. The precise measurement of the refractive index showed that refractive index of LiCAF dose not change by the Mg2+ doping, within the doping range of Mg2+<1.0mol%.
