From Wikipedia, the free encyclopedia

An Er:YAG laser (erbium-doped yttrium aluminium garnet laser, erbium YAG laser) is a solid-state laser whose active laser medium is erbium-doped yttrium aluminium garnet (Er:Y3Al5O12). Er:YAG lasers typically emit light with a wavelength of 2940 nm, which is infrared light.

The output of an Er:YAG laser is strongly absorbed by water. As a result, they are widely used for medical procedures in which deep penetration of tissues is not desired.

Erbium-YAG lasers have been used for laser resurfacing of human skin.[1] Example uses include treating acne scarring, deep rhytides, and melasma. In addition to being absorbed by water, t...
