Аннотация:Invariants of three- and four-wave interactions of femtosecond pulses are constructed with allowance for dispersion of the nonlinear response of the medium and wave self-action. The analysis is based on a novel transformation of the system of generalized Schrödinger equations into a form containing no derivatives of the nonlinear response of the medium. The invariants can be used as a basis for constructing conservative difference schemes and finding soliton solutions that describe harmonic generation.
