Paper Abstract

We consider physical principles of realizing the Bragg regimes for a two- and three-phonon light scattering in both optically and acoustically anisotropic tellurium dioxide crystal under specially elaborated conditions. The exact analytical models for describing these regimes are briefly discussed. The performed analysis demonstrates the principal possibilities of realizing 100% efficiency of light modulation in these regimes, and computer simulations illustrate the obtained results. The applications lie in the fields of exploiting large aperture spatial modulators of light. The main attention was paid to estimating the frequency bandwidths as well as the frequency resolution of such modulators.
