Paper Abstract

We have demonstrated that a polarization-insensitive anisotropic dynamic grating can be used to detect accident mode hopping in long-cavity-length fiber ring lasers. The polarization-insensitive property of the grating is realized by a Faraday rotator mirror and validated experimentally. The mode hopping properties of a particular single-longitudinalmode erbium-doped fiber ring laser is examined by an anisotropic grating with 3-m long erbium doped fiber. When mode hopping occurs, the grating responds a negative intensity peak. Repeated measurement shows that the continuing cavity length wandering during the laser operation is the origin of the accident mode hopping when there is no modulation applied to the cavity length.
