Abstract

We demonstrate experimentally and theoretically that the sign of two-wave coupling gain in sillenite crystal at some polarization of light changes with the increase of the amplitude of square-wave field applying along the axis. It is shown that the nonunidirectional energy exchange is the reason of this effect in Bi₁₂TiO₂₀ single crystal. Such energy exchange is bound with the contribution of the self-diffraction gyration effect into the efficiency of the two-wave interaction. At the theoretical analysis we used the mode obtained on the basic of the mode approach. Made the numerical calculation of the dependency of the two-wave coupling gain on the amplitude applied field has god agreement with the experimental data. This calculation has allowed estimating the material parameters of the investigated samples of the crystal.
