Paper Abstract

The coupling of two waves in barium titanate is described in terms of scattering matrices derived from a vector coupled wave theory. Key mechanisms responsible for the processes of self-pumped phase conjugation and beam fanning are identified, and the role of reflections from the internal faces of the crystal are examined. The nonlinear effects observed in the crystal are considered in terms of theory and methods of controlling the photorefractive coupling strength in the crystal are considered. Applications for controlling the coupling in photorefractive crystals are also considered.
