two-inch 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 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.
