Abstract
We study the process of two-wave mixing (TWM) in optically active, electra- optic, and elasto-optic BSO and BTO crystals. We calculate the TWM gain for arbitrary crystal cut and optimize the energy exchange. For the (111) cut, by choosing an appropriate coordinate system, we obtain a simple analytica l solution for the components of the coupling tensor which allows us to opt imize analytically the TWM gain with respect to the grating orientation and the initial light polarization.
