YVO4

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 and other polarizing optics, etc.

      It is well known that YVO4 crystal growth and fabrication are much easier than that of TiO2 (too high hardness) and CaCO3 crystals (easy cleavage and its susceptibility to moisture), so its price is very competitive compared to that of other similar crystals. Accordingly, it is much more practical than TiO2 and CaCO3 crystals. Since high optical quality YVO4 crystal is available easily in large quantities, it is substituting step by step TiO2 and CaCO3 crystal as relevant optical components.
