Home/Technical Glossary/Nd:YVO4 Laser Nd:YVO4 Laser An Nd:YVO4 laser – more commonly known as “Vanadate” – is a laser in which the active gain medium is neodymium-doped yttrium orthovanadate: Nd:YVO4 Nd:YVO4 lasers are optically pumped using either a flashlamp or laser diode array. They typically emit light with a wavelength of 1064 nm, but may also operate at 914 nm or 1342 nm. Common applications include marking, engraving, spectroscopy and research.
