A Novel Double-Brillouin-Frequency Spaced Multi-wavelength Brillouin Erbium-doped Fiber Laser Based on Non-linear Amplified Fiber Loop Mirror

提出了一种基于非线性放大光纤环形镜(AFMLF)滤波器的双倍布里渊频移间隔的多波长掺铒光纤激光器(MWBEL)环形腔结构,其中非线性放大光纤环形镜被用作滤波器。当980nm泵浦功率为10.29dBm、可调激光源(TLS)的中心波长为1 563nm、功率为-3dBm时,得到了波长间隔为0.16nm的12阶偶数阶多波长激光输出。同时,还研究了980nm抽运功率、偏振控制器(PC)以及可调激光源的中心波长对输出斯托克斯光波数的影响。

In the paper, a ring double-Brillouin-frequency spaced multi-wavelength Brillouin Erbium-doped fiber laser （MWBEL） based on non-linear amplified fiber loop mirror filter （AFMLF） was demonstrated, in which the non-linear amplified fiber loop mirror was used as a filter. At the 980 nm pump power of 10.29 dBm, the tunable laser source centre wavelength of 1 563 nm and power of -- 3 dBm, up to 12 even output channels with 0. 16 nm spacing were achieved. And also the influences of 980 nm pump power, the polarization controller and the tunable laser source centre wavelength on the number of Stokes light wave were studied.
