Er:YAG laser Information & Er:YAG laser Links at HealthHaven.com

Er:YAG lasers are solid-state lasers whose lasing medium is erbium-doped yttrium aluminium garnet (Er:Y₃Al₅O₁₂). Er:YAG lasers typically emit light with a wavelength of 2940 nm, which is infrared. Unlike Nd:YAG lasers, the frequency of Er:YAG lasers is strongly absorbed by water due to atomic resonances. This limits its use in surgery and many other laser applications where water is present. Because of this limitation Er:YAG lasers are far less common than relatives such as Nd:YAG and Er:glass.

Er:YAG lasers have been used for laser resurfacing.^[1] Example uses include treating acne scarring, deep rhytides, and melasma. In addition to water, Er:YAG laser energy is also absorbed by hydroxyapatite, which makes it a very good laser for cutting bone as well as tissue. Bone surgery applications have been found in oral surgery, dentistry, implant dentistry and otolaryngology.^[2]^[3]^[4]^[5]
