In this paper, we experimentally and theoretically investigate the stability and uniformity of multi-wavelength Brillouin-erbium fiber laser based on four-wave mixing (FWM). Multi-wavelength generation is limited by cross-gain saturation between different wavelengths from homogeneous broadening of erbium-doped fiber. Modeling coupled-mode equation for FWM and analyzing the influence of FWM on multi-wavelength generation. 16 orders Brillouin Stokes (BS) waves with a wavelength spacing of 0.084 nm are obtained experimentally within a 3 dB bandwidth by the FWM effect in a 100 m highly nonlinear fiber (HNLF), power distribution of each laser is uniform and peak power fluctuation is less than 1.184 dB within a 10 dB bandwidth, the outputs exhibit good time stability and uniformity. Compared with the same configuration, the laser without HNLF has only 9 orders stable BS waves within 3 dB bandwidth, and high-order Stokes wave shows significant waveform jitter and power fluctuation.
