摘　　要：为了获得高质量的可调谐多波长激光器,提出并验证了一种结构简单的基于受激布里渊散射(SBS)放大效应的多波长激光器。首先设计了单频布里渊环形腔激光器,将单频激光信号作为信号光,通过SBS放大效应实现了超过12个波长的激光输出,且产生的波长数可以进一步增加。该激光器的波长间隔为0.087nm,通过调节泵浦波长和功率实现了可调谐的多波长输出。在20min的时间间隔内,测量了信号的稳定性,实验结果表明,本文的多波长激光器展现了较高的稳定性。In order to obtain high quality tunable multi-wavelength laser, a novel approach of generating tunable multi-wavelength Brillouin fiber laser is proposed and experimentally demonstrated. In this scheme, the single-longitudinal-mode Brillouin ring cavity laser is designed and obtained. And then, by using the single frequency laser as signal light, based on Brillouin amplification effect, the multi-wave- length laser with more than 12 wavelengths has been obtained, and the wavelength number can be further increased. The wavelength interval of the laser is about 0. 087 nm,and the tunable output of multi-wavelength can be realized by adjusting the pump wavelength and power. In 20 min interval, the stability of the multi-wavelength laser is measured,and the experimental results show that the multi-wavelength laser has high stability.
