Er:YAG laser stands for Erbium-doped Yttrium Aluminum Garnet laser. It is a type of solid-state laser that uses erbium ions (Er³⁺) as the active laser medium, with yttrium aluminum garnet (YAG) as the host crystal. The Er:YAG laser operates at a wavelength of approximately 2940 nanometers, which falls within the infrared spectrum.
