我国Nd:YAG激光晶体的研制工作始于1965年。70年代初期研制成提拉法生长的掺钕钇铝石榴石晶体,经不断改进光学质量和增大尺寸,80年代初期已能研制出系列化产品,并可向国外出口,目前研制单位约十几个,产值达到数百万元。在有一定规模和一定数量的情况下,产品的质量成为各研制单位十分关注的问题,为了相互交流技术,曾在全国组织过多次不同规模的学术交流会,1982年前曾对产品质量作过两次全国性的统一测试,为全国性的YAG晶体质量评比打下了基础。为此,国家科委新技术局委托电子部激光专业情报网与电子部11所主办首届全国Nd:YAG激光晶
China Nd: YAG laser crystal development work began in 1965. In the early 1970s, the neodymium-doped yttrium aluminum garnet crystal, which was grown by the Czochralski method, has been developed into a serialized product through continuous improvement of optical quality and size. At the beginning of the 1980s, it can be exported to foreign countries. At present, about ten Several, the output value reached millions of dollars. In a certain scale and a certain number of cases, the quality of the product has become a very concerned issue of the development unit, in order to exchange technology, has organized in the country many times of different sizes of academic exchanges, prior to 1982 on product quality After two nationwide unified tests, the national YAG crystal quality appraisal laid the foundation. To this end, the State Science and Technology Commission commissioned by the New Technology Bureau of the Ministry of Electronics Laser Information Network and the Ministry of Electronics 11 hosted the first national Nd: YAG laser crystal
