As one of the mechanisms for stable multiwavelength oscillation in a fiber Raman ring laser, an inhomogeneous loss induced by intraline four-wave mixing in a fiber Raman laser is physically explained and experimentally validated by comparison of laser peak gain and power gain as well as the gain spectra at several pump levels.
