在光纤环形腔中加入基于光纤布拉格光栅的法布里-珀罗滤波器和可变饱和吸收体，实现了一种单纵模光纤环形腔激光器。利用FBG F-P滤波器和可变饱和吸收体的组合模式滤波，实现了超窄带滤波器。不需要精确控制腔长，并且可以方便地实现稳定的单模工作而没有模式跳变。
A single-longitudinal-mode (SLM) fiber ring laser is demonstrated by incorporating a fiber Bragg grating (FBG)-based Fabry–Perot (F–P) filter and a variable saturable absorber in a fiber ring cavity. An ultra-narrow bandpass filter is established by the combined mode filtering of the FBG-based F–P filter and the variable saturable absorber. No accurate control for cavity length is required, and stable single longitudinal-mode operation without mode hopping is conveniently achieved.
