Abstract
The purpose of this work is to find a reliable approach for one- and two-dimensional acousto-optic deflector design. The design method is based on an improved theoretical model of anisotropic acousto-optic interaction. The new feature of this model is the application of new approximations together with the inclusion of effects that were previously neglected, such as optical beam divergence, second order diffraction and optical activity. Configurations for maximum efficiency and maximum resolution are shown. Optimization of the two-dimensional deflector design is presented. The reliability of the model is demonstrated at wavelengths of 633 and 1064 nm through experimental results with devices designed based on the new model for TeO 2 deflectors.
