We experimentally propose simple and widely tunable multiwavelength Brillouin erbium fiber laser with triple Brillouin frequency spacing. Only two dispersion compensation fiber spools with total length of 12 km, as a Brillouin gain media and erbium-doped fiber amplifier section with maximum pump power of 220 mW are utilized. In the developed structure, we achieved six triple Stokes lines with high peak power and large optical signal to noise ratio of more than 45 dB. Wide tuning range of 50 nm (1530–1580 nm) in the absence of self lasing cavity modes is recorded using both of high Brillouin pump and extracting the residual pump power outside the cavity.
