ABSTRACT

ZnO-doped near-stoichiometric LiNbO3 single crystals of 0.8~1.0 mm diameter and 30~35 mm length were grown by the micro-pulling down (m-PD) method. The structure of the grown crystals was confirmed by powder x-ray diffraction (XRD) patterns. Electron probe micro analysis (EPMA) showed that Zn ions were homogeneously incorporated in grown crystals. The threshold in ZnO doping level was confirmed that an abrupt change in the features of OH- absorption band as doping level reaching about 2 mol%.
