Abstract
The asymptotic equations governing the envelope of a quasi-monochromatic optical pulse in a non-resonant x(2) material are derived. Under rather general assumptions, equations of nonlinear Schrödinger (NLS) type with coupling to mean fields result. In relevant physical situations either scalar or vector systems are obtained. Special reductions include the usual scalar and vector NLS equations. Based on results of similar systems a brief discussion of some of the properties of the equation is included.
