Abstract

Possibilities of optimization of the characteristics of light diffraction on holographic gratings and two-wave mixing in a cubic gyrotropic photorefractive piezocrystal with the help of choice of crystal orientation and polarization of light waves are investigated. It is shown, that dependences of optimum azimuth (Psi) ₀^max of light waves polarization, at which maxima of diffraction efficiency (eta) ^max and effective gain (gamma) ^max are reached, on orientation angle (theta) differ on 90 degree in area 90 degree less than or equal to (theta) less than or equal to 270 degree and practically coincide in other cases.
