Abstract

Four kinds of lithium niobate crystals doped with Cu:Ce, Mn:Cu:Ce, Mn:Fe, and Mn:Fe:Mg processed under oxidation or reduction conditions are studied experimentally for the photorefractive non-volatile holographic storage with the first scheme, i.e with ultraviolet light sensitizing and red light recording. On the condition of non-volatile holographic storage with high signal-to-noise ratio, the non-volatile diffraction efficiency of the oxidized LiNbO₃:Cu:Ce crystal is the highest among all studied samples. The non-volatile holographic storage in the oxidized LiNbO₃:Cu:Ce crystal is performed with the second scheme, i.e with blue light sensitizing and red light recording, and the intensity of the blue light is optimized.
