Paper Abstract

Zr:Fe:LiNbO3 crystals with various of [Li]/[Nb] ratios were grown by Czochralski technique from melts having compositions varying between 46-58 mol% Li2O. The compositions of the growth crystals were determined by the inductively coupled plasma technique (ICP-AES). The defect structures were analyzed by UV-vis spectroscopy. The photorefractive properties of the Zr:Fe:LiNbO3 were investigated by using two-beam coupling experiment. The results showed that as the [Li]/[Nb] ratio increased, the diffraction efficiency decreased, but photorefractive sensitivity increased , and the response time decreased.
