We have successfully grown LiCaAlF_6 and Ce,Na:LiCaAlF_6 Single crystals by the Czochralski method. Grown crystals were free of detrimental OH group. It was found that grown crystals had Li enriched composition and the segregation coefficient of Ce was 0.01. Tunability of Ce,Na:LiCaAlF_6 laser was confirmed at the wavelength region from 275nm to 320nm.
