Paper Abstract

We study theoretically an opportunity of shaping three-wave coupled states within a strong co-directional collinear acousto-optical interaction between two optical waves and the suffering losses acoustic pulses in a square-law nonlinear crystal. The developed analytical model for this process with the mismatched wave numbers describes a regime of coupled modes, which is considered analytically, using the first order approximations as well as qualitative estimations, and simulated numerically. The comparison of results from these two approaches demonstrates their acceptable agreement with each other. Three-wave collinear acousto-optical coupled states originating within such an interaction exhibit a remarkable asymmetry in shapes of their envelopes and a shift of extrema in the intensity distribution for each wave component.
