Neodymium-doped Yttrium Orthovanadate Description

Neodymium-doped Yttrium Orthovanadate (Nd:YVO4) is a crystal that is widely used in solid-state lasers. It belongs to the orthorhombic crystal system and has the chemical formula YVO4.

Nd:YVO4 is a highly efficient laser crystal due to its excellent thermal, mechanical, and optical properties. The neodymium (Nd) dopant is added to provide a lasing transition at a wavelength of around 1064 nanometers, which is in the near-infrared region. This makes Nd:YVO4 an ideal material for producing high-power, continuous-wave, and pulsed lasers.

Nd:YVO4 is extensively used in various applications, including telecommunications, materials processing, medical procedures, spectroscopy, and scientific research. It offers high absorption and emission cross-sections, low threshold for lasing, high gain, and good beam quality.
