The Solver for Nonlinear Optical Propagation SNOPROP code models the interaction of intense lasers with background media in two dimensions. This report derives the envelope propagation equations for an intense laser beam including self- and cross-phase modulation, first order Stokes and anti-Stokes stimulated Raman scattering, and four-wave mixing. Ionization is included using a multiphoton and collision alionization model. We also discuss the implementation of the solver and the numerical methods used as well as demonstrate a basic example of underwater laser propagation featuring the effects mentioned above.
