Abstract
The interest for Brillouin fiber ring lasers has significantly increased due to the large spectrum of their applications: the large scale of their peak power, the ultra-narrow linewidth and the low threshold power are the most exploited features. At the same time, their application is limited because of the important peak-power fluctuations which are mainly due to the stochastic nature of the Spontaneous Brillouin Scattering that initiates the Stimulated Brillouin Scattering (SBS). Therefore, it is of great interest to develop new models and methods for controlling these amplitude fluctuations. Several analytical and numerical solutions are often proposed to describe the steady state of the SBS in single mode optical fibers but, for instance, the general form of the non-linear equations system of the SBS is difficult to solve. Models start typically from the classical system [1] which couples the evolution of two optical fields with the acoustic field through the electrostriction process and propose several improvements to obtain a better agreement with experimental data or predict new behaviors.
