【摘要】 为满足神光装置发展和未来国家XX工程对激光玻璃工作物质的大量需求,中国科学院上海光学精密机械研究所研究了激光玻璃连续熔炼工艺技术。激光玻璃连续熔炼是一种全新的工艺技术,先后攻克了除水、除铂、降低过渡金属杂质、澄清、成型条纹和炸裂等一系列关键单元技术,使连续熔炼激光玻璃的荧光寿命、光吸收、光学均匀性等指标达到神光装置的使用要求,并与坩埚熔炼的激光玻璃性质进行了比较;2010年对各单元技术进行集成,取得了合格样片。2011年对取得的成果进行验证实验,获得小批量样品,标志着激光玻璃的连续熔炼取得了阶段性的成功。2012~2013年进行激光玻璃连续熔炼中试实验,取得较好成果。更多还原

【Abstract】 To keep pace with the development of SG device and the great demand of laser glass materials for the national XX project in the near future,Shanghai Institute of Optics & Fine Mechanics,Chinese Academy of Science undertook a research on the continuous melting technology for producing laser glass. Continuous melting process of laser glass is a new technology,which has overcome the key technical difficulties,such as water removal,platinum elimination,transition metal impurity reduction,refining,cord in forming process and crack,etc. The fluorescence lifetime,light absorption and optical homogeneity index of laser gass produced by continuous melting technology all met requirements of Shenguang devices’ application,and were compared with that produced by galss pot melting process. In2010 those single technological progresses were integrated and a qualified sample was obtained. Experimental verification of the obtained results was conducted in 2011 and a small quantity of samples wasprepared that means the continuous melting technology for laser glass has achieved a staged success. In the years of 2012 ~ 2013,the pilot production of continuously molten laser glass was carried out and achieved good results.更多还原
