Self-seeded multiwavelength Brillouin-erbium fiber linear cavity laser

We have proposed and demonstrated a novel multiwavelength Brillouin-erbium fiber laser (BEFL) with a linear cavity, in which, the Brillouin pump is self-excited within the cavity, doesn't require the injection from the external cavity or direct generation within the intracavity. In this scheme, more than 115 Stokes lines with relatively uniform amplitudes have been generated. The experiment also demonstrates that such a self-seeded BEFL performs good repetition and stability for both the operating wavelengths and the output power of each Stokes line. Meanwhile, the effect of the 980nm pump on the performance of the laser is investigated.
