✦ Synopsis
A low threshold and efficient multi-wavelength Brillouin-erbium fiber laser with a pre-amplified Brillouin pump within a Fabry-Perot cavity is presented. With the utilization of a fiber Bragg grating filter as one of the fiber loop mirrors, up to 25 stable Brillouin Stokes lines could be generated with channel spacing of 0.088 nm. The architecture of the design consumes only 3 dBm of the Brillouin pump power and 90 mW of the 980 nm laser diode to produce the 25 maximum output channels. The signal to noise ratio of each channel was also observed to be not less than 20 dB.
