Abstract
An opportunity of shaping three-wave solitary coupled states within the co-directional collinear acousto-optical interaction between two optical waves and the suffering losses acoustic pulses in a square-law nonlinear crystal. The considered analytical model for this process with the mismatched wave numbers describes a regime of strongly coupled modes. They are studied using the first order approximations relative to a pair of the parameter of smallness. We assume that both the acoustic losses and the wave number mismatch represent these pair of the smallness parameters of the same order. Three-wave collinear acousto-optical coupled states originating within such an interaction exhibit an asymmetry in shapes of their envelopes and shifts of extrema in their intensity distributions.
