Two-Dimensional Dynamics of Solitons under the Conditions of Zakharov–Benney Resonance

Resumo

The generation of terahertz radiation by optical pulses under quasi-resonance conditions in a medium of asymmetric quantum particles is considered. A system of nonlinear wave equations describing this process is derived for a noncollinear geometry when the direction of the phase velocity of optical pulses does not coincide with that of the terahertz pulse radiation. Different types of solutions of the resulting system of equation are studied.
