BaTiO3 is an excellent photorefractive crystal for self-pumped
phase conjugation, four-wave mixing and many other photorefractive processes.
It has high beamcoupling gain and short beam-coupling rise time. The highest
SPPC reflectivity was reported by using BaTiO3 , It can be operated at
visible and near-infraced regions and is good for cw four-wave mixing
with milliwatts optical power.
