Paper Abstract

In the two-color nonvolatile holographic data storage, ultraviolet light sensitization and visible light bleaching are two important processes. The selection of the wavelength of ultraviolet light and visible light has a profound impact on the recording and readout performance. We have studied experimentally the absorption spectra of some samples of typical doubly doped lithium niobate crystals, such as Mn:Fe:LN, Cu:Ce:LN, Cu:Fe:LN, etc., under the condition of ultraviolet light sensitization and visible light bleaching respectively. By choosing different wavelength of ultraviolet light and visible light, we have obtained some useful results of material properties. Finally, simple theoretical analysis are given and the appropriate wavelength of ultraviolet light and visible light for two-color nonvolatile holographic storage are suggested corresponding to each kind of crystal above.
