摘要：

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 2 mm in diameter. The flexibility and lower cost of this growth technique will markedly reduce the cost of growing laser grade crystals.
