Paper Abstract

We investigate the phenomena, which are similar to effects of the quantum teleportation and of superluminality, at the two-wave interaction in a medium with the quadratic and cubic nonlinear responses taking place simultaneously. The interaction of two femtosecond tosecond pulses occurs under the conditions of a group velocity mismatch. The formation of sub-pulses at both frequencies, part of which demonstrate soliton properties with a velocity higher or lower than the velocity of linear pulse propagation in considering condition at the same group velocity dispersion, is revealed. The reason of an acceleration of the sub-pulse is the induced periodic grating o dielectric permittivity. Consequently, the acceleration of the light pulse is due to tunneling through these gratings. It is very important that the gratings are absent before the interaction of laser radiation with the medium. The second important feature is the following. For each fast sub-pulse there is a pulse whose velocity is smaller than the velocity of the linear propagation. Hence, the preservation of an impulse of whole pulse takes place. The interesting property of the formed structures is the sensitivity of each of the anomalously propagating sub-pulses to perturbation introduced in the other sub-pulse at a chosen cross section. Another sub-pulse changes instantaneously at the perturbation of the given sub-pulse. This is similar to the effect of the quantum teleportation.
