Yttrium Vanadate (Nd:YVO4) Crystals. Yttrium Vanadate (Nd:YVO4) crystals are positive uniaxial crystals grown using the Czochralski method. They have good mechanical and physical properties and are ideal for optical polarizing components because of their wide transparency range and large birefringence. They are an excellent synthetic substitute for Calcite (CaCO3) and rutile (TiO2) in many applications including fiber optic isolators and circulators, beam displacers, Glan polarizers and other polarizing optics.
