18 Years Factory Passive Q-Switches - Undoped YVO4 crystal – Dien

Undoped YVO 4 crystal is an excellent newly developed birefringence optical crystal and widely used in many beam displace online_orderings because of its large birefringence. It also has good physical and favorable mechnical properties than thers birefringent crystals, those outstanding properties make YVO4 very important birefringence optical material and widely used in opto-electronic research, development and industry. For example, the optical communication system needs a large quantity devices of undoped YVO4, such as fiber optical isolators, circulators, beam displacers, Glan polarizers and other polarizing devices.

Feature:

●  It has very good transmission in a wide wavelength range from visible to infrared.
●  It has high refractive index and birefringence difference.
●  Compared with other important birefringence crystals, YVO4 has higher. hardness, better fabrication property, and water insolubility than calcite (CaCO3 single crystal).
●  Easier to make large, high quality crystal at lower cost than Rutile (TiO2 single crystal).
