Strontium-Barium Niobate (SrxBa(1-x)Nb2O6) SBN: 61 and SBN:75 composition crystals have an excellent optical and photorefractive properties. Nominally pure and doped by Ce, Cr, Co or Fe. SBN crystals of different compositions are used in elecro-optics, acousto-optics, and photorefractive non-linear optics.
High optical quality SBN single crystals growed by Modified Stepanov technique are free of growth striations, inclusions and other inhomogeneities.
Custom size, dopping, unpoled, AR coated or crystals without electrodes are available on request.
