BGO Single Crystal (Bismuth Germanate, Bi₁₂GeO₂₀) Substrates

Product Overview
BGO (Bi₁₂GeO₂₀) is a sillenite-type electro-optic and photorefractive single crystal used in photonics, holography, optical information processing. This cubic crystal exhibits photorefractive and nonlinear optical properties, high refractive index, and chemical and mechanical stability. With the stated density and radiation-response characteristics, BGO crystals are used for optical research, electro-optic devices.
