In this paper,a novel linear multi-wavelength Brillouin erbium-doped fiber laser (EDFL) is demonstrated.We utilize a nonlinear amplified fiber loop mirror filter (AFLMF).The nonlinear amplified fiber loop mirror filter consists of erbium-doped fiber amplifier (EDFA) with a segment of erbium-doped fiber pumpe d by 980nm laser diode,a polarization controller (PC) and an optical coupler.The nonlinear AFLMF induces wavelength- dependent cavity loss and it can provide flexibility on controlling the amount of light reflected and transmitted into and out of the laser′s cavity.At the Brillouin pump power of 25mW and the 980nm pump power of 200mW,14output channels with 0.08nm spacing and tuning range of 50nm from 1530nm to 1580nm are achieved.And we realize the tunable output of multi-wavelength through adjusting the 980nm pump power,the polarization cont roller and the Brillouin pump wavelength.In addition,the effects of both 980nm pump power and PC on the waven umber of Stokes light are studied.
