布里渊掺铒光纤激光器(BEFL)是一种利用非线性效应——布里渊散射来实现多波长输出的激光器, 波长间隔大约为0.088nm(11GHz)。研究了一种多波长布里渊掺铒光纤激光器线形结构, 通过引入反馈实现多波长输出。在布里渊泵浦功率为11mW, 980nm泵浦功率为12mW时获得了波长间隔为0.08nm 的34个波长的激光输出以及1525~1570nm可调谐范围。并通过调节980nm抽运光功率以及布里渊泵浦光波长, 实现了可调谐的多波长输出。 还研究了980nm抽运光功率对产生的斯托克斯光波数的影响。

In this paper, a linear multiwavelength Brillouin-Erbium fiber laser based on Stimulated Bullouin scattering was demonstrated. An efficient multiwavelength Brillouin-Erbium fiber laser was developed by using the feedback mechanism of Brillouin Stokes lines. At the Brillouin pump power of 11mW and the 980nm pump power of 12mW, 34 output channels with 0.08nm spacing and tuning range of 45nm from 1525nm to 1570nm were achieved. And it is realized the tunable output of multi-wavelength through adjusting the 980nm pump power and the Brillouin pump wavelength. In addition, the effects of 980nm pump power on the number of Stokes light wave are studied.
