BaTiO3 Crystal

Crystals >>> Photorefractive Crystals >>>  BaTiO3 Crystal

Barium Titanate or BaTiO3 is an excellent photorefractive crystal for self-pumped phase conjugation, four-wave mixing and many other photorefractive processes.  It has high beam- coupling 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.
