In these lasers, a section of Erbium doped fiber without undergoing bump used as saturatable absorber. A self-written grating may be formed by stable standing wave in this absorber. Because selfwritten grating possesses a characteristic of very narrow rejection band and can suppress any other side-band effectively, so the multi-longitudinal mode and mode jumping in other normal fiber ring laser are removed in this one.
