Energy exchange optimization in (110)-cut BTO crystal by choice of interacting waves polarization

The relative intensity dependence of a signal wave on the orientation angle between holographic grating vector and crystallographic axis [0 0 1] is ex perimentally found for the first time for fixed thickness of (1 1 0)-cut BT O crystal in the case of two-wave mixing. Azimuth of polarization of intera cting waves corresponding to maximum energy exchange is theoretically found for every value of the orientation angle. Comparison of theoretical and ex perimental orientation dependencies of gain for two special linear polariza tions (in the incidence plane and perpendicularly to this one) and maximum gain is fulfilled as well.
