Abstract
A series of Zr(1 mol%):Cu(0.1 mol%):Fe(0.03wt%)LiNbO3 single crystals with various Li/Nb ratios having compositions varying between 48.6 and 58 mol% Li2O in the melt were grown by the Czochralski method in the air. The OH transmittance spectra was investigated to characterize the structure defects of these crystals. The OH absorption peaks shift to longer wavelength as the [Li]/[Nb] ratio increases and an obvious absorption peak at 3468 cm-1 was observed at the Li/Nb ratio of 1.05. The photorefractive properties of the crystals were experimentally studied using the two-wave coupling method. The results show that as the [Li]/[Nb] ratio increases, the holographic response time and the diffraction efficiency increase under the Li/Nb ratio of 1.2.
