Abstract
We present the consideration of parametrically coupled solitary waves developing via codirectional collinear acousto-optical interaction in an optically anisotropic medium under action of a pulsed incident light wave. Both the cases of a strong an weak coupling are theoretically studied and then, the analysis of weakly coupled acousto-optical states with pulsed optical pump is extended to the regime with mismatched wave numbers. Such a phase mismatch enables us to shape and investigate the coupled acousto-optical states experimentally using the pulsed incident light at relatively low power density of acoustic pulses. A new digital programmable modulator capable of controlling over the binary encoded trains of optical pulses is proposed and developed. Results of our experiments with such a device are also presented and briefly discussed.
