Abstract

We describe the successful growth of a laser quality Ce3+: LiCaAlF6 crystal using the micro-pulling down method. The crystal is grown using less than one gram of raw material and a pulling rate of 0.1 mm/min. Ultraviolet laser emission at 290 nm with 23% slope efficiency and 1 mJ pulse energy is demonstrated from a Brewster-cut crystal, which is 30 mm in length and 2mm in diameter. The flexibility and lower cost of this growth technique will markedly reduce the cost of growing laser grade crystals.
