Аннотация:Invariants of nonlinear interaction of femtosecond pulses with matter characterized by noninstantaneous response are constructed so as to take into account the linear dispersion in the three leading orders and the dispersion of the nonlinear medium response. To construct the invariants, the generalized Schrödinger equation is transformed so as to eliminate the derivatives of the nonlinear response. The resulting equation is well suited for numerical simulation. The invariants obtained can be used to design conservative finite-difference schemes and verify results provided by numerical experiments.
