The surface of the normal component of the inverse tensor of the dielectric permittivity of a cubic photorefractive piezoelectric Bi12SiO20 crystal was constructed. A volume phase holographic grating with a wave vector along the \( \left[1\overline{1}1\right] \) crystallographic axis was recorded in this crystal. It is established that the combined action of the photoelastic and piezoelectric effects leads to an increasing normal component of the inverse tensor of the dielectric permittivity along the \( \left[1\overline{1}1\right] \) direction and a decreasing normal component of the inverse tensor of the dielectric permittivity in the perpendicular direction. It is revealed that the anisotropy of the contribution of the photoelastic and piezoelectric effects causes an increase in the output energetic characteristics (optimized in the azimuth of polarization of light waves) for the transmission hologram and their decrease for the reflection hologram.

光弹和压电效应对光折变晶体中透射和反射全息图能量特性的影响
构造了立方光折射压电Bi 12 SiO 20晶体的介电常数的反张量的法向分量的表面。在该晶体中记录了具有沿\(\ left [1 \ overline {1} 1 \ right] \)的波矢量的体相全息光栅。可以确定,光弹效应和压电效应的共同作用导致介电常数的反张量的法线分量沿\(\ left [1 \ overline {1} 1 \ right] \)增大介电常数的反张量的垂直方向和垂直方向的递减法线分量。揭示了光弹性和压电效应的贡献的各向异性导致透射全息图的输出高能特性的增加(在光波的偏振方位角上最优化),而对于反射全息图则减小。
