Abstract

A series of LiNbO₃:Fe:Mn:Zr crystals with different ratios of Li/Nb in the melt (0.94,1.05,1.20 and 1.38, respectively) were grown by the conventional Czochralski technique. The ultraviolet-visible spectra were measured in order to analyze the defect structure of the crystals. The measurement of the Zr concentrations and Li/Nb ratios in the crystals was carried out with an inductively coupled plasma atomic emission spectrometer. The light-induced scattering was investigated as a function of exposure energy. The results showed that the ability to resist the light-induced scattering was improved considerably with the increase of the Li/Nb ratio. The relationship between the defect structures and the light-induced scattering was discussed.
