Acoustical vector solitons in anisotropic media

Resumo

A theory of acoustical vector solitons of self-induced transparency in anisotropic media is developed. It is shown that, in these systems, a two-component vector soliton oscillating with the difference and sum of the frequencies in the vicinity of the frequency of a carrying acoustic wave may arise. Explicit analytical expressions for the form and parameters of a nonlinear wave depending on the direction of pulse propagation are given.
