摘要：
An efficient multi-wavelength Brillouin fiber laser (BFL) is demonstrated by using a self feedback mechanism of Brillouin-Rayleigh scatterings with the presence of distributed Raman gain. The balanced of these three scatterings generates a laser comb more than 27 lines, with a relatively flat amplitude and constant spacing of 0.09 nm. This is realised using a piece of dispersion compensating fiber as the nonlinear gain medium, an amplified Brillouin pump and a broad-band fiber Bragg grating is a reflector.
