active medium
81alexandrite laser — a laser whose active medium is alexandrite doped with chromium, emitting light in the mid infrared spectrum and tunable between 701 and 826 nm and used usually at 755 nm; used for hair removal and other dermatologic procedures …
82carbon-dioxide laser — a laser with carbon dioxide gas as the active medium that produces infrared radiation at 10,600 nm; used to excise and incise tissue and to vaporize …
83erbium:YAG laser — a laser whose active medium is a crystal of yttrium, aluminum, and garnet doped with erbium ions, and whose beam is in the near infrared spectrum at 2940 nm; used for photoablation and photocoagulation and for a variety of dermatologic procedures …
84helium-neon laser — a laser with a mixture of ionized helium and neon gases as the active medium whose beam is in the red visible light spectrum at 633 nm; used as a guiding beam for lasers operating at nonvisible wavelengths …
85holmium:YAG laser — a laser whose active medium is a crystal of yttrium, aluminum, and garnet doped with holmium ions, and whose beam is in the near infrared spectrum at 2100 nm; used for photocoagulation and photoablation …
86ion laser — a laser that uses one of the inert gases (argon, helium, neon, or krypton) as the active medium …
87krypton laser — a laser with krypton ionized by electric current as the active medium whose beam is in the yellow red visible light spectrum; used for photocoagulation …
88neodymium:yttrium-aluminum-garnet (Nd:YAG) laser — a laser whose active medium is a crystal of yttrium, aluminum, and garnet doped with neodymium ions, and whose beam is in the near infrared spectrum at 1060 nm; used for photocoagulation and photoablation …
89tunable dye laser — a dye laser whose active medium can be altered so that the beam has any of several wavelengths …
90YAG laser — a type of laser whose active medium is a crystal of yttrium, aluminium, and garnet. It is used for cutting tissue, for example in lens capsulotomy or iridotomy. Specialized types (e.g. the holmium:YAG laser) are used for various purposes …
