Anisotropic Selfdiffraction in KNbO3

Not Accessible

Your library or personal account may give you access

Abstract

Holographic recording of information in electrooptic crystals is based on a light- induced modulation of the elements of the dielectric tensor. For readout of these volume phase holograms the Bragg condition must be satisfied[1]. In birefringent crystals this may be achieved not only for waves with equal polarization (isotropic diffraction) but also for orthogonally polarized waves (anisotropic diffraction) [2].
