Large single crystals of have been grown with as the flux by the top-seeded solution growth method. The crystal is chemically stable and easily polished and absolutely insensitive to moisture. The obtained crystals are bounded by a combination of well-developed rhombohedron and hexagonal prism faces. The crystal is found to be transparent from 180 to 3300 nm. The refractive indices were measured with the minimum-deviation method and fitted to the Sellmeier equations. The nonlinear optical coefficient of measured by the Maker fringes technique is (KDP).
