Abstract

The absorption spectra and the optical damage resistance ability of the In:Fe:LiNbO₃ crystals grown by Czochralski method with different concentration of In₂O₃ were measured. The absorption edges of the absorption spectra of the In:Fe:LiNbO₃ crystals shift to the short wavenumbers with the concentration of the In₂O₃ in the crystal increasing. The optical damage resistance ability of the In(3.0mol%):Fe:LiNbO₃ crystal is two orders magnitude higher than that of Fe:LiNbO₃ crystal. The response speed of the In:Fe:LiNbO₃ crystals increases with the concentration of the In₂O₃ in the crystal increasing, on the contrary, the diffraction efficiency decreases.
