Nd: YVO4 Crystal Characteristics

YVO4 crystal is an excellent birefringent optical crystal newly developed in recent years. It has good light transmittance in a wide range of visible and near-infrared, with a large refractive index and poor birefringence rate . Compared with other important birefringent crystals, YVO4 crystal is harder than icelandite (CaCO3 single crystal), has good mechanical processing performance, is insoluble in water, and can be grown artificially (icelandite depends on natural resources); YVO4 crystal is also It is easier to grow large high-quality crystals than rutile (TiO2 single crystal), and the price is much lower than rutile. These excellent characteristics make YVO4 crystal quickly become a new type of birefringent optical material, which is widely used in the optoelectronic industry. In optical fiber communication equipment, a large number of various light splitting and polarization components made of pure YVO4 crystals, such as optical isolators, circulators, optical beam splitters, and Glan series polarizers, are required. The combination of YVO4 crystals and rutile crystals can also obtain ideal temperature compensation effects and greatly improve the temperature stability of the optical communication system.
