Abstract

In:Zn:LiNbO₃ crystals have been grown by Czochralski technique. The infrared transmission spectra of the samples showed that the OH- absorption peak of In(3mol.%):Zn(3mol.%):LiNbO₃ located at about 3508cm^-1, while those of In(1mol.%):Zn(3mol.%):LiNbO₃ and In(2mol.%):Zn(3mol.%): LiNbO₃ located at about 3485cm^-1. The photo-damage resistant ability of the crystals was measured with the directly facula-distort observing method. The results showed that, when doped In³⁺ and Zn²⁺ concentration reached their threshold concentration, the photo-damage resistant ability of In(3mol.%):Zn(3mol.%):LiNbO₃ was two orders of magnitude higher than that of pure LiNbO₃. Second harmonic generation (SHG) experimental results showed that the phase matching temperature of In(3mol.%):Zn(3mol.%):LiNbO₃ was almost at room temperature, and their SHG efficiency was higher than that of Zn(7mol.%):LiNbO₃ and pure LiNbO₃.
