Abstract

Doped MgO and In₂O₃ in Fe:LiNbO₃ through Czochralski technology to grow Mg:In:Fe:LiNbO₃ crystal for the first time. The photo-scattering resistance ability of Mg(3mol%):In(3mol%):Fe:LiNbO₃ crystal were measured. It improves the two orders magnitude higher than that of Fe:LiNbO₃ crystal. The absorption spectra of the Mg:In:Fe:LiNbO₃ crystals were tested. The absorptive edge was found to shift to the short wavelength. The infrared spectra of the crystals were measured, when Mg²⁺ and In³⁺ reach their threshold concentration in crystal, the absorption peak shifts from 3484cm^-1 to 3520cm^-1. Two wave coupling method was used to test the diffraction efficiency and response time of the crystals. The response speed of the Mg:In:Fe:LiNbO₃ crystal is higher than that of the Fe:LiNbO₃ crystal.
