摘　　要：通过使用非线性放大的光纤环形镜滤波器(AFLMF),构造了一种新颖的多波长布里渊掺铒光纤激光器(EDFL)线形结构。非线性AFLMF由掺铒光纤放大器(EDFA,由980nm泵浦抽运一段EDF构成)、偏振控制器(PC)和耦合器构成,减少了腔内基于波长的损耗,并且能够灵活地控制反射光以及激光腔内输入和输出光的强度。在布里渊泵浦功率为25mW、980nm泵浦功率为200mW时,获得了波长间隔为0.08nm的14个波长的激光输出以及50nm的可调谐范围。通过调节980nm抽运光功率、PC以及布里渊泵浦光波长,实现了可调谐的多波长输出。研究了980nm抽运光功率以及PC对斯托克斯光波数的影响。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 pumped by 980 ran 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 25 mW and the 980 nm pump power of Z00 roW, 14 output channels with 0.08 nm spacing and tuning range of 50 nm from 1530 nm to 1580 nm are achieved. And we realize the tunable output of multi-wavelength through adjusting the 980 nm pump power, the polarization controller and the Brillouin pump wavelength. In addition,the effects of both 980 nm pump power and PC on the wavenumber of Stokes light are studied.
