Paper Abstract

In the present work, a simple scheme for a Raman distributed fiber laser is proposed. The lasing scheme is based in the combination of two random cavities which act as distributed mirrors when pumped by a single laser. The distributed mirrors are created as a consequence of Rayleigh scattering and double Rayleigh scattering formed in the dispersion compensating fiber as a result of the high Raman gain. The proposed distributed fiber laser presents stable operation at room temperature, showing a maximum variation of ~0.09dBm in a 30 minutes time window. The output spectrum of the distributed fiber laser presents a broadband bandwidth of 10nm with a 30dBm signal to noise ratio. This configuration allows suppression of the Rayleigh associated noise growth typical in Raman lasers, while using it as an active part of the laser cavity.
