Strontium-barium niobate (SrxBa(1-x)Nb2O6, SBN:x, x=61, 75) crystals have excellent optical and photorefractive properties. They are available nominally pure and doped by Ce, Cr, Co or Fe dopants. Different composition SBN crystals found their application in electro-optics, acousto-optics, photorefractive, non-linear optics fields. 4Lasers provide free from inclusions and other inhomogenities SBN crystals, which are grown by Modified Stepanov method and available with linear dimensions up to 40 mm.
