The Yttrium Orthovanadate(YVO4) is a positive uniaxial crystal grown with Czochralski method. It has good temperature stability and physical and mechanical properties wide transparency and large birefringence, so it is also ideal for optical components such as fiber optical isolators and circulators, beam displaces, interleavers and other polarizing optics, etc.
