Paper Abstract

A novel short-cavity-based narrow linewidth random fiber laser (RFL) is proposed. The random distributed feedback mechanism of RFL is assumed by a set of arbitrarily distributed weak reflection fiber Bragg grating arrays (FBGs). A π-phase-shifted FBG with a narrow transmission window is used in the RFL to further limit the number of random subcavity modes and suppress the output linewidth. High gain erbium-doped fibers and half-open cavity designs are used to maintain low lasing thresholds. A stable single-mode lasing operation with 3-dB linewidth of 211 Hz and 58 dB sidemode-suppression-ratio is established.
