Photorefractive BaTio<SUB>3</SUB> single crystal were successfully prepared by a combination of Top-Seeded Solution Growth technigue and suitable poling processes. The single crystals were grown from the melt which was the mixture of TiO<SUB>2</SUB>/BaCO<SUB>3</SUB>=65/35 in molar ratio. The employed sources of TiO<SUB>2</SUB> and BaCO<SUB>3</SUB> were 99.99% and 99.999% purity powders, respectively. The asgrown crystal boules, the dimensions of about 20x 20x 15mm<SUP>3</SUP>, were cut into 3-5mm rectangular prisms. Subsequently, the crystals were polished, and domain walls of those were removed by applying uniaxal compressive stress and electrical field.<BR>The obtained crystals, whose phase transitions were clearly observed at about 130°C by DSC measurement, exhibited typical ferroelectricity. And furthermore, self-pumped phase conjugation was observed in the single domain BaTiO<SUB>3</SUB> crystals by using an argon ion laser operating at 515nm.
