Abstract
Stimulated Brillouin scattering (SBS) is commonly used for light amplification in fiber cavities enabling a variety of laser performance characteristics. Backward Rayleigh scattering (RS) is the backscattered part of the linear elastic light scattering on “frozen” fiber index non-uniformities. When an external feedback in the fiber is strongly suppressed, Rayleigh backscattering is able to provide a feedback to the Stokes field generated through Brillouin scattering leading to the pronounced cooperative effect now known as Brillouin random lasing [1]. Here we report the result of external acoustic and temperature noise on the random fiber laser performance.
