A generalization of the method of slowly varying amplitudes to nonlinear optics of femtosecond pulses makes it possible to determine the limits of applicability of the nonlinear Schrodinger equation, the maximum contraction of the pulses, and the conditions for the decay of a wave packet into "color" solitons.
