Abstract
We deal with the vectorial equations of two-wave mixing without an external field (diffusion response) in Bi12SiO20 and Bi12TiO20 by splitting the vec torial amplitudes of signal and reference waves into a parallel part whose direction is determined by the optical activity rotation and into a perpend icular part. By doing so we obtain an approximation scheme that works parti cularly well after optimization with respect to the input polarization. Exp loring the relevant crystal configurations [L, T, and D geometry of the (11 0) cut and T ' and D ' geometry of the (111) cut], we show that for common crystal thicknesses our approximate solution is almost as precise as the nu meric solution.
