Some possibilities for improving the holographic recording characteristics in Bi12Si020monocrystals

On the basis of detailed consideration of the influence of a number of factors such as recording and readout light intensity, condition of preliminary illumination, electrical contact properties, parameters of the applied external electric field (direct and alternating), and the anisotropic properties of light diffraction from a simple hologram (diffraction grating), possibilities are sought for optimal conditions of holographic recording in crystal of the type Bi
