提出了一种结构新颖的多波长环形腔掺铒光纤激光器，在其结构中采用了一种新型梳状滤波器，该滤波器由一个光纤光栅非对称写在一个Sagnac环中来实现，具有设计简单、易于制作、成本低和插入损耗小等优点。实验中得到了非常稳定的三波长和双波长激光输出，线宽均小于0.06 nm，输出波长间隔分别为0.34 nm和0.5 nm，输出功率差异分别在2 dB和0.4 dB内，消光比分别为～40 dB和～50 dB。

A novel multi wavelength erbium-doped fiber ring laser is presented, which employs a novel comb filter based on a fiber Bragg grating asymetriclly written in a Sagnac interferometer. The filter has advantageous of simple design and fabrication, low cost and low insertion loss. Stable triple-wavelength and dual-wavelength laser operations with wavelength spaces of 0.34 nm and 0.5 nm, respectively, and output power differences of <2 dB and <0.4 dB, respectively, have been demonstrated.
