Paper Abstract

Mg:Fe:LiNbO3, Ce:Fe:LiNbO3 and Fe:LiNbO3 crystals were grown by the Czochralski method. The absorption spectra of these crystals were measured. It is shown in the results that the absorption edge of Mg:Fe:LiNbO3 shifts to violet while that of Ce:Fe:LiNbO3 shifts to red in comparison with that of Fe:LiNbO3. In the measurement of the photo scattering resistance ability of Fe:LiNbO3 and Mg:Fe:LiNbO3, it is found that the photo scattering resistance ability of Mg:Fe:LiNbO3 is two orders of magnitude higher than that of Fe:LiNbO3. The four wave mixing properties, such as the phase conjugate reflectivity and the response time, of the crystals were obtained. Among the three crystals, Ce:Fe:LiNbO3 has the largest phase conjugate reflectivity, and Mg:Fe:LiNbO3 has the shortest response time. Using Mg:Fe:LiNbO3 crystal as the storage material and Ce:Fe:LiNbO3 as phase conjugate reflector, the associative storage was realized.
