In recent years, multi-wavelength fiber lasers play a significant role in plenty of fields, ranging from optical communications to mechanical processing and laser biomedicine, owing to their high beam quality, low cost, and excellent heat dissipation properties. Benefitting from increasing maturity of optical elements, the multi-wavelength fiber laser has made rapid developments. In this review, we summarize and analyze diverse implementation methods covering continuous wave and pulsed fiber lasers at room temperature conditions: inserting an optical filter device and intensity-dependent loss structure in the resonant cavity, and applying ultrafast nonlinear optical response of materials and a dual-cavity structure. Finally, future challenges and perspectives of the multi-wavelength fiber laser are discussed and addressed.

针对超短脉冲光纤激光器光谱线宽较大的问题进行研究, 利用RP Fiber软件对激光器腔内脉冲演化过程进行模拟计算, 分析了几种可饱和吸收体对激光器输出脉冲宽度和线宽的影响, 并对激光器的腔长和光纤布拉格光栅(FBG)参数进行了优化。最终, 根据优化结果, 搭建了一种基于WS2可饱和吸收体的环形腔被动锁模皮秒脉冲掺铒光纤激光器, 并利用窄带FBG对输出脉冲的光谱线宽进行压缩, 获得了中心波长为1549.4 nm、脉冲宽度为171 ps的窄线宽超短脉冲输出, 其3 dB光谱线宽为0.02 nm。
