Paper Abstract

It is known that the incorporation of a self-induced grating in a saturable absorber can be used to drive fiber ring lasers to single-mode operation with ultra-narrow linewidth output. However, ultra-narrow linewidth erbium-doped fiber ring lasers (EDFRLs) usually suffer inevitably environmental perturbations for the relatively long resonant cavity, which may deteriorate the single-mode stability and practical applications in optical coherence detection. In this paper, the singlemode stability of the EDFRL under low-frequency resonant cavity disturbances has been investigated experimentally, and the induced mode hops have been measured to demonstrate that the occurrence of mode hopping can be triggered regularly by stretching the cavity fiber. The phenomenon of induced mode hopping indicates that the self-induced grating can only dynamically adjust itself to small disturbances in the cavity parameters within a finite range.
