Popis:	An efficient multi-wavelength Brillouin fiber laser incorporating fiber Bragg grating is presented by using the ring cavity technique. With the utilization of fiber Bragg grating’s reflectivity, up to maximum 28 Brillouin Stokes signals with 15.65 dB of average optical signal to noise ratio are generated with constant downshifted frequency of 0.08 nm. The laser system consumes 18 dBm of amplified Brillouin pump power and 90 % of the output coupling ratios at 11 km of single mode fiber. The Brillouin pump wavelength was fixed at 1550 nm corresponds to the center wavelength of fiber Bragg Grating. The optical signal to noise ratio was also observed to be not less than 13.05 dB at 18 dBm of amplified Brillouin pump power in all cases of the output coupling ratios.
