摘要
Using Si Mo bar as heater and doping Fe 2O 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.
