Paper Abstract

Ce-doped tungsten bronze Ba2-xSrxK1-yNayNb5O16 (BSKNN) ferroelectric crystals have A been grown by the Czochralski technique, Rand arefound to be of optical quality with excellent photorefractive properties. Although the BSKNN crystals studied have a tetragonal bronze structure at room temperature, their growth habits are different: BSKNN-1 grows in a square shape with four well-defined facets, while BSKNN-2 crystals have an octahedron shape with eight well-defined facets. Ferroelectric and optical measurements show these crystals to have strong longitudinal effects similar to perovskite BaTiO3 and excellent self-pumped phase-conjugate behavior.
