《今日电子》2004年第8期报导:针对目前多由气体激光器来满足应用需要,日本NTT公司开发出一种能够制作可生成指定波长的固态激光器技术,这是以往用半导体器件所无法实现的。这项技术将半导体的性能优势引入了过去无法使用此类器件的应用领域。该技术采用铌酸锂非线性光学晶体,将具有不同输出频率的两个入射激光的输出组 “Today’s Electronics” No. 8, 2004 Report: For the current multi-gas lasers to meet the needs of the application, Japan’s NTT company has developed a capable of generating the specified wavelength of solid-state laser technology, which is previously impossible with semiconductor devices . This technology brings the performance advantages of semiconductors into applications that were not possible with such devices in the past. The technology uses lithium niobate non-linear optical crystal, with different output frequency of two incident laser output group
