主　　题：Multi-wavelength fiber laser distributed feedback fiber laser narrow linewidth fiber laser 

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.
