Abstract

We present a new photorefractive crystal (Ce:BaTiO₃) with superior photorefractive properties. The formation of a self-pumped phase conjugate (SPPC) wave is based on backward photorefractive scattering. For a 0-degree-cut and a 45- degree-cut Ce:BaTiO₃ crystals the SPPC reflectivities of 70% and 83.5% were achieved at lambda equals 515 nm respectively. It has been experimentally demonstrated that this crystal is probably the most efficient self-pumped phase conjugator in the visible spectral regime so far.
