<title>Effect of parametric processes on the stimulated Raman scattering in fibers</title>

Abstract

We present experimental results for an investigation of both parametric and Raman scattering processes simultaneously occurring in optical fibers. The generation of Stokes as well as of anti-Stokes components under the influence of the parametric effects, is considered. The generated new optical frequencies can yield more favorable conditions concerning the material dispersion and the losses in fibers. Substantially nonlinear regime of interaction with a mutual exchange between the excited radiation and the generated signal frequencies is analyzed by solving the full system of equations with account of the real and imaginary parts of the nonlinear optical susceptibility.
