Growth and optical properties of In:Nd:LiNbO3 crystals

In, Nd double-doped LiNbO3 (LN) crystals have been grown for the first time. Their infrared (IR) transmission spectra were measured and discussed to investigate their structure and defects. The optical damage resistance of Nd:In:LiNbO3 crystals were characterized by straightly observing transmission facula distortion method. The optical damage resistance of In (4.0mol%):Nd:LiNbO3 was much higher than that of Nd:LiNbO3. The defects were discussed in this paper to explain the optical damage resistance in the In:Nd:LiNbO3 crystals.
