Abstract

The ultraviolet-visible and the infrared absorption spectra of co-doped crystals with 0.03wt.% Fe₂O₃ and various concentrations of M(M=In,Mg) were detected to investigate their defect structures. By increasing the concentration of M, we observed a shift of the absorption edge and OH-peak for MNb(M replaces the normal Nb sites) when M exceeded its threshold value. The shift of the OH-absorption peak in Mg:Fe:LiNbO₃ is larger than that in In:Fe:LiNbO₃. At the same time, the optical damage resistance ability of M:Fe:LiNbO₃ crystals is two orders of magnitude higher than that of Fe:LiNbO₃ crystals.
