Abstract

We report on a frequency-stabilized narrow-linewidth continuous-fiber erbium-doped ring fiber laser in which the operating wavelength is defined by an overlay filter. The oscillating frequency is stabilized by a side-of-fringe locking technique, and longitudinal mode hops are inhibited by phase-sensitive detection of the signal rejected from an intracavity all-fiber étalon. With this frequency-stabilization scheme resolution-limited linewidths of 68 kHz with a root mean square frequency jitter of 10 kHz are measured. The oscillating frequency is continuously tunable over 3 GHz.
