4Photorefractive dynamic holography

4.1 INTRODUCTION

The photorefractive dynamic holography uses a different type of non-linear optical effect known as photorefractive effect. The photorefractive effect occurs in certain crystals of sillienite family like Bismuth Germanium Oxide (Bi12GeO20 or BGO), Bismuth Silicon Oxide (Bi12SiO20 or BSO), Bismuth Titanium Oxide (Bi12TiO20 or BTO) and polar crystals like Barium Titanate (BaTiO3), Lithium Niobate (LiNbO3) etc[23-26]. The photorefractive effect occurs in these crystals when the refractive indices change due to optically induced spatial distribution of electrons and holes when two beams interfere inside these crystals. The photorefractive effect phenomena is different from conventional non-linear ...
