本文报道了氟化物激光晶体Nd3+: LiYF4的坩埚下降法生长工艺.采用经氟化处理的无水氟化物原料,按照LiF: YF3 = 51.5 : 48.5的比例配料,控制炉体温度于920960C,晶体生长速度为0.40.8 mm/h,通过密闭条件下的坩?埚下降法生长出尺寸为25mm80mm的完整单晶.
The growth process of fluoride laser crystal Nd3+: LiYF4 by Bridgman method was reported. By using raw materials treated by fluoridation, and matched withthe composition ratio of LiF: YF3=51.5:48.5, a high quality fluoride laser crystal Nd3+: LiYF4 with a large-size of 2580 mm was grown under nearly sealed conditions.
