A common nonlinear phenomenon in dielectrics is Raman-scattering. It is an indirect resonant, dissipative process, which is best described in terms of a third-order nonlinear polarization. In the following, we show how to integrate a material model for Raman-active dielectrics into a numerical discontinuous Galerkin time-domain scheme for two and three-dimensional systems. To this end, we present a scheme of auxliliary differential equations by which we describe the process of stimulated Raman-scattering.
