中文摘要：

一种狭窄的线宽激光配置基于有在国际电信联合(ITU ) 的八波长的分布式的反馈纤维激光(DFB-FL ) ，格子被介绍并且认识到。在这种激光配置，在系列的八个转移阶段的栅栏被二根 980-nm 激光二极管(LD ) 双向地抽。最后的激光产量与在 10-mW 上，为每波长的力量能被获得，并且在八波长以内的最大的力量差别是 1.2 dB。有多重波长和一致力量产量的激光配置能在大放大光纤维水中听音器地里是很有用的。

英文摘要：

A narrow linewidth laser configuration based on distributed feedback fiber lasers （DFB-FL） with eight wavelengths in the international telecommunication union （ITU） grid is presented and realized. In this laser configuration, eight phase-shifted gratings in series are bidirectionally pumped by two 980-nm laser diodes （LDs）. The final laser output with over 10-mW power for each wavelength can be obtained, and the maximum power difference within eight wavelengths is 1.2 dB. The laser configuration with multiple wavelengths and uniform power outputs can be very useful in large scaled optical fiber hydrophone fields.
