Abstract

It is well known that the picosecond time duration range optical solitons dynamics described by the nonlinear Schrodinger equation (NSE) has provided remarkable accord between theory and experiment. There is a gap of understanding as to the fundamental features of solitons when going to the femtosecond range and the envelope contains only a few optical periods. Up to date no answer has been obtained to the key question of the nonlinear optics of femtosecond pulses. This question is what is the ultimate width of a pulse that can be produced and how to produce pulses with the width t = T, that is, optical videopulse without a high-frequency field component?
