%X A kind of Mg-doped near stoichiometric LiNbO3 crystal was grown with Czochralski method from a stoichiometric melt with addition of llmol% K20 and lmol% MgO. Compared with congruent LiNbO3 crystal, its ultraviolet absorption edge shifts towards short wavelength and the location and shape of the OH- infrared absorption band also change distinctly, so that the Mg2+ doping concentration can be considered as having reached the optical damage resistant threshold concentration. Acid etching result shows that the crystal has regional single domain structure.
