Abstract

Propagation of the ultrashort pulses of the electromagnetic wave was considered in framework of the anharmonic oscillator model. For the quasi-harmonic waves, the model leads to the description of quadratic parametric processes, e.g., sum-frequency and difference-frequency mixings. Unipolar steady state pulse was obtained by analytical method. In numerical simulations it was shown that these steady state pulses are stable under collisions and small harmonic perturbations. However, these pulses are not solitons in the strict sense. Multipolar pulses demonstrate the stable regime of propagation too if these pulses exhibit a few oscillation of the electric field and the energy of these impulse is fairly high.
