In the present work, a multiwavelength fiber laser based in the
combination of a double-random mirror and a suspended-core Sagnac
interferometer is presented. The double-random mirror acts by itself as a
random laser, presenting a 30dB SNR, as result of multiple Rayleigh
scattering events produced in the dispersion compensating fibers by the
Raman amplification. The suspended-core fiber Sagnac interferometer
provides the multi peak channeled spectrum, which can be tuned by
changing the length of the fiber. The result of this combination is a stable
multiwavelength peak laser with a minimum of ~25dB SNR, which is
highly sensitive to polarization induced variations.
