Diffraction from the Second-Order Photorefractive Grating in Paraelectric KTa1-xNbxO3 Crystals
-
Abstract
Diffraction from the second-order photorefractive grating written in KTa1-xNbxO3 (x=0.32) crystal with cubic phase has been observed for the first time. The behaviors of this diffraction have been investigated experimentally. Some qualitative explanations have been proposed.
