Yttrium vanadate YVO4

　　Yttrium vanadate (YVO4) single crystal is a birefringent crystal material with excellent physical optical properties. The crystal has a wide range of light transmission, high transmittance, large birefringence coefficient and is easy to process. Therefore, YVO4 crystal is widely used in the field of optical fiber communication and is the key material in optical communication passive devices such as optical isolators, polarimeters, retarders, polarizer.
