Motion of space-charge waves in LiNbO3:Fe

During the dark relaxation of phase holograms written in electrooptic LiNb03:Fe crystals, the holograms undergo a spatial displacement. This observational fact is linked with a propagation of trap charge-exchange waves in the crystal. The dispersion of these waves, ω~Κ~χ, agrees with the experimental results.
