摘　　要：采用密闭反应气氛电阻加热熔体提拉法与上称重自动控径技术生长稀土离子掺杂氟化钇锂系列(Re∶YLF)激光晶体,通过优化热场设计,有效地解决了大尺寸YLF系列激光晶体生长过程中的开裂和直径控制起伏的问题,成功生长出了直径大于50 mm的YLF系列激光晶体,晶坯无晶界、基本无散射,光学均匀性良好。同时开展了YLF系列激光晶体热扩散键合技术研究,通过定向切割、轴向匹配和面形匹配光胶、构造高温度均匀性热键合温场,成功制备出了YLF键合激光晶体。A series of rare-earth ion doped YLF laser crystals were grown using resistance heating with closed reaction atmosphere, czochralski method and up-weighing ADC technique. By optimizing the thermal design, effectively solves the problems of cracking and diameter control fluctuations in the growth process of large size YLF laser crystals. YLF with no grain boundary, no scattering and diameter greater than 50 mm were successfully grown. At the same time, the thermal diffusion bonding technology of YLF laser crystal was studied. By directional cutting, the axial surface shape matching, matching optical cement and constructing heat bonding temperature field with good temperature evenness, YLF bonding crystals were successfully prepared.
