Yttrium orthovanadate (YVO4) is a birefringent optical crystal that has a tetragonal crystal structure. It exhibits strong birefringence and a high refractive index, which makes it useful in various optical applications.
One of the key applications of YVO4 is as a substrate for the growth of thin films of other materials, such as superconductors and ferroelectric materials. YVO4 has a high degree of crystallographic orientation and is able to provide a high-quality surface for the growth of these films.
YVO4 is also used as a birefringent material in various optical devices, such as wave plates, polarizers, and frequency doubling crystals. Its strong birefringence allows it to split light into two orthogonal polarizations, each traveling at a different speed and refracting at different angles.
In addition to its optical applications, YVO4 is also used as a host material for the doping of rare earth ions, such as neodymium and erbium, which can be used to produce solid-state lasers. These lasers have a wide range of applications, including in materials processing, telecommunications, and medical equipment.
