Attention! You can customise this product to your needs.
Nominally pure and doped by Ce, Cr, Co, Fe SBN crystals (SBN:61, SBN:75) of different compositions are used in elecro-optics, acousto-optics, photorefractive non-linear optics. A new growing technique (Stepanov Method) provides excellent optical quality single crystals, free of growth striations, inclusions and other inhomogeneities, as well as definite cross section and linear dimensions up to 80 mm.

SBN crystalline elements meet the requirements for different applications. Based on this unique crystal growing technique, large high quality SBN optical elements and photorefractive cells are available.

Special dopants Ce, Cr, Co, Ni, La, Tm, Yb, Nd Ce+La, Ce+Ti, Ce+Cr.


● Two-wave mixing: optical information recording, dynamic holographic interferometry, optical holographic amplifier.
● Four-wave mixing: highly efficient phase conjugation, self pumped phase conjugation mirror, double phase conjugation mirror.
● Electro-optical elements, acousto-optical elements.
● Pyroelectrical detectors.
● Self-frequency doubling, self-sum-frequency mixing of laser and pump radiations.
