Design of optimization technique for electro- and acousto-optical interactions of light in crystalline materials

In this paper new approach to the spatial anisotropy 3D-analysis of electro- and acousto-optical effects on the basis of indicative surfaces for different components of tensor describing these effects has been proposed and the optimization technique for such interactions of light with electrical field or acoustical wave in the crystalline materials has been designed. This technique is demonstrated for researched crystals of barium beta-borate, langasite and pure and MgO-doped lithium niobate as prospective acousto- or electro-optic materials.
