Nd: YAG

Nd:YAG (neodymium-doped yttrium aluminium garnet) is a crystal that is used as a laser medium for solid-state lasers. Nd:YAG lasers are used in manufacturing for engraving, etching, or marking a variety of metals and plastics, or for metal surface enhancement processes like laser peening. The most common wavelength for Nd:YAG laser is 1064 nm, but Nd:YAG lasers can also produce other wavelengths through frequency doubling, tripling, and quadrupling, for example 532 nm, 355 nm, and 266 nm. Typical use for these lasers includes cutting and welding steel in manufacturing applications, semiconductors and various alloys. Medical uses for Nd:YAG include skin treatments for cancers, treating varicose veins, spider veins, and thread veins, facial veins, vascular birthmarks, and vascular tumors. Nd:YAG lasers are widely used in surgery, including endoscopy, urology, neurosurgery, ENT, gynecology, dental surgery, and general surgery. They can also be used to treat ophthalmology conditions, such as acute angle-closure glaucoma and diabetic retinopathy. Hair removal can also be performed with Nd:YAG lasers.

Even with brief exposure Nd:YAG lasers can cause irreversible eye damage, therefore proper laser safety glasses are critical for eye protection.
