Аннотация:Previously constructed invariants of three- and four-wave interaction of femtosecond pulses with matter are generalized so as to take into account third-order dispersion. For the equations describing second- and third-harmonic generation, the third invariant is shown to be universal in the sense that it can be used to derive another independent invariant. Invariants are also found for multiwave interaction of pairs of counter-propagating femtosecond pulses, which has not been considered previously. To construct the invariants, the system of generalized Schrödinger equations is transformed so as to eliminate the
