提出了一种可调谐多波长布里渊掺铒光纤激光器结构。利用由光环行器构成的光纤环形镜和环形腔，形成双向反馈结构，可以有效降低布里渊阈值。该激光器实现了在1513~1578 nm之间超过65 nm范围可调谐的激光输出。当布里渊抽运功率为15 dBm(32 mW)，980 nm抽运功率为23 dBm(200 mW)时获得了波长间隔为0.08 nm的11个波长的激光输出。

A tunable multiwavelength Brillouin-erbium fiber laser is demonstrated. With the mirror constructed by the optical circulator and the ring-cavity, a bidirectional feedback structure is constituted to reduce the Brillouin threshold. This fiber laser provides a tuning range of 65 nm from 1513 nm to 1578 nm. At the Brillouin pump power of 15 dBm (32 mW) and the 980 nm pump power of 23 dBm (200 mW), 11 output channels with 0.08 nm channel spacing are achieved.
