大尺寸非线性光学晶体三硼酸氧钇钙的研究进展

Progress on Research of Crystal Growth of Large-Size Nonlinar Optical Crystal Yttrium Calcium Oxyborate

近年来，惯性约束聚变点火工程将Ca4YO（BO3）3（简称YCOB）晶体视作快点火核聚变装置中频率转换器件中非线性材料的重要候选，大尺寸YCOB晶体的生长成为其获得重大应用的关键。结合最近几年的研究工作以及国内外YCOB晶体的生长情况，介绍了YCOB晶体的生长情况特别是大尺寸晶体生长的研究进展，并对将来的生长研究的前景进行了展望。

Recently, YCOB crystal is regarded as material candidate of frequency conversion devices in fast ignition facility, thus large size YCOB crystal growth becomes an important key problem. The crystal gowth of YCOB, specially for large size YCOB crystal, is reviewed based on the research details in the world and prospected.
