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 amplitu
In this paper, a multiwavelength linear-cavity Brillouin-Erbium fiber laser pumped by a 1480 nm pump laser is demonstrated to operate in the L-band region. The issue of low gain efficiency of L-band in Erbium-doped fiber pumped with 980 nm pump lasers is resolved with this pumping scheme. The amount
