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
