Abstract

The processes of amplification of holographic grids connected with different components of spacial spectrum of images in photorefractive crystals have been investigated theoretically and experimentally. The amplification effects were studied experimentally with a slightly doped LiNbO₃ crystal. If (lambda) equals 0.63 micrometers the amplification was up to 15 dB, alternatively, if (lambda) equals 0.44 micrometers it was more than 50 dB.
