Title: Diffraction from the Second-Order Photorefractive Grating in Paraelectric KTa <sub>1-x</sub> Nb <sub>x</sub> O <sub>3</sub> 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.
