Ordinary and extraordinary few-cycle optical solitons in the uni-axial crystals

摘要

Transverse-longitudinal dynamics of few-cycle pulses, propagation under any angle to axis of the optical anisotropy of uniaxial crystal is researched. In such media pulses are divided on ordinary and extraordinary components, interacting between itself in nonlinear mode. It is shown that spectrum of ordinary wave depends on sign of birefringence and angle of propagation. Condition on the wave length of transverse perturbations under which diffraction able to suppress self-focusing is received.
