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