提出并实现了一种通道数独立可调的多波长拉曼光纤激光器。它采用了一种新型的自由光谱范围（FSR）可调谐梳状滤波器的基础上叠加啁啾光纤布拉格光栅（CFBG）和线性腔形成的带宽可调谐的CFBG反射器，泵浦的高非线性光纤的拉曼增益，和基于环形镜的光环行器。实现了多波长激光操作，间隔可调范围为0.3 ~ 0.6nm，通道数可调范围为2 ~ 10。
A spacing-tunable multiwavelength Raman fiber laser with an independently-adjustable channel number is proposed and demonstrated. It uses a novel free-spectral-range (FSR)-tunable comb filter based on a superimposed chirped-fiber Bragg grating (CFBG) and a linear cavity formed by a bandwidth-tunable CFBG reflector, a pumped highly-nonlinear fiber for Raman gain, and an optical circulator based loop mirror. Multiwavelength laser operations with spacing tuning from 0.3 to 0.6 nm and channel number adjustment from 2 to 10 have been achieved.
