Abstract

Bismuth tellurite has a unique feature, a long-living (years) photorefractive memory that develops in the four-wave mixing process without fixing. Single crystals of Bi2TeO5 were grown by the Czochralski method. The Bi/Te ratio and the oxygen equilibrium were found to be the major factors modifying the crystal quality. The systematic improvement of the growth technique has led to enhanced photorefractive figure of merit for Bi2TeO5.
