In this research work, we introduce a simplified structure of multi-wavelength Brillouin-erbium-ytterbium fiber laser that incorporates only a single amplifier source. A total of 146 output channels are produced with a channel spacing of 0.246 nm. A quality optical signal-to-noise ratio of 46.2 dB is realized along the 36 nm lasing bandwidth that starts at 1533 nm wavelength. For this particular area of fiber lasers, the obtained results confirm dramatic advancements in spectral flatness and stable output channels count combination. This enhances the merit and competitiveness for many practical applications, namely fiber sensing and optical communications.
