BaTiO3 Crystals

BaTiO3(Barium Titanate) crystal is an excellent crystal with superior photorefractive properties. We provide many new types of BaTiO3 crystal products such as Ce:BaTiO3crystal and Rh:BaTiO3 crystal to expand the wavelength range of photo refractive effect, and 45-deg cut device to increase the photo refractive efficiency.
