Abstract

Mg:Fe:LiTaO₃ crystals were first grown by Czochralski method, and Fe:LiTaO₃ crystals, Fe:LiNbO₃ and Mg:Fe:LiNbO₃ crystals were also grown at the same time. The holographic storage properties of these crystals, such as the exponential gain coefficient, the diffraction efficiency and the response time, were measured by the two-wave coupling method. It was found that the response speed of Mg:Fe:LiTaO₃ crystal was five times faster than that of Fe:LiTaO₃. The light scattering resistance ability was also measured, and that of Mg:Fe:LiTaO₃ crystal was two orders of magnitude higher than that of Fe:LiTaO₃ as well as higher than that of Mg:Fe:LiNbO₃. The enhancement mechanism of the photorefractive properties for Mg:Fe:LiTaO₃ crystal was discussed for the first time.
