Its wavelength ranges from about 800 nm to 1 mm and it is emitted particularly by heated objects. ---- 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]]. infrared_light.txt Last modified: 2024/06/07 02:59by 127.0.0.1
