Growth and holographic storage properties of Fe:LiTaO3 crystal

Using Si-Mo bar as heater and doping Fe 2 O 3 in LiTaO 3 , Fe: LiTaO 3 crystal was grown by Czochralski method. The curie temperature of the crystal was measured by thermal analyze method. The lattice constants of the crystal were calculated by measuring of X-ray spectra. The response time, exponential gain coefficient and diffraction efficiency of Fe: LiTaO 3 were obtained by two wave coupled technique. Compared with Fe:LiNbO 3 , the response time of Fe: LiTaO 3 is six times shorter, the storage time of Fe: LiTaO 3 is ten times longer and the photo scattering resistance ability of Fe: LiTaO 3 is four times higher. Fe: LiTaO 3 is an excellent holographic storage material.
