Quasicollinear acoustooptical interaction in three-dimensionally optically inhomogeneous crystals
A theoretical model is given for the quasicollinear acoustooptical interaction of beams in a three-dimensionally optically inhomogeneous, anisotropic medium. Analytical solutions of the coupled wave equations are obtained for a regular linear inhomogeneity model in relation to the spatial profiles of the frequency spectrum of the diffracted field. The spatiospectral transfer functions are determined, and their selective properties are investigated for various orientations and magnitudes of the gradient of the optical inhomogeneity for both low and high diffraction efficiencies. Numerical simulation results are given.
