Er:YAG is an acronym for Erbium-doped Yttrium Aluminium Garnet (Er:Y3Al5O12), a compound that is used as the lasing medium for certain solid-state lasers. Er:YAG lasers typically emit light with a wavelength of 2940 nm, in the infrared. Unlike in Nd:YAG lasers, the frequency of Er:YAG lasers is at the resonant frequency of water, which leads it to being quickly absorbed; this limits its use in surgery and many other laser applications which have water present. Because of this limitation Er:YAG lasers are far less common than relatives such as Nd:YAG and Er:glass.
