Growth and photorefractive properties of Zr:Cu:Fe:LiNbO3 crystals with various Li/Nb ratios
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.
