Transmissive effect in BaTiO_3 self-pumped phase conjugators

The transmissive effect in BaTiO3 crystal self-pumped phase conjugators was studied from the dependence of the emergent angle of the transmitted phase conjugate beam on the incident angle of the pumping beam, the light path of the transmited phase conjugate beam in a BaTiO3 crystal, and its transmissivity versus the angle between the pumping beam and c axis of a crystal. It was found that there indeed exists a transmitted phase conjugate beam in the self- pumped phase conjugation of a BaTiO3 crystal and the transmitted beam is separated from the self-pumped phase conjugate beam by an internal reflection of the crystal surface.
