Abstract
A significant decrease is observed in the dielectric dispersion, conductivity, coercive and internal fields of near stoichiometric KTiOPO 4 crystals. A periodic domain structure with a period of 24.7 μm was fabricated on a 10-mm long crystal by electric field poling. Whereas standard flux-grown KTiOPO4 crystals can be periodically poled only at low temperatures (near 170 K), the periodic poling in this case was successfully performed near room temperature at a much lower electric field
