介绍了在普通通讯用单模ＧｅＯ２／ＳｉＯ２石英光纤中从近红外到可见光的频率上转换过程。利用１．３１３μｍ的调Ｑ锁模ＮｄＹＬＦ激光脉冲泵浦单模石英光纤，产生了５８８ｎｍ的黄光，峰值功率达２０Ｗ，对应０．０９％的转换效率。同时在４６０ｎｍ～５６０ｎｍ范围内有三波混频的兰绿光产生，其光谱呈多峰结构。实验中还观察到兰绿光与黄光之间强度上的竞争现象
The frequency conversion from near infrared to visible light in single mode GeO2 / SiO2 quartz fiber for general communications is introduced. Single-mode quartz fiber was pulsed with a 1.313μm Q-switched NdYLF laser to generate 588nm yellow light with a peak power of 20W, corresponding to a conversion efficiency of 0.09%. At the same time in the 460nm ~ 560nm range of three-wave mixing blue-green generation, the spectrum showed a multi-peak structure. The experiment also observed the intensity of the competition between blue-green light and yellow light
