Laser surgery is a type of surgery that uses a laser (in contrast to using a scalpel) to cut tissue. Types of surgical lasers include carbon dioxide, argon, Nd:YAG laser, and potassium titanyl phosphate, among others.
This is a list of laser types, their operational wavelengths, and their applications. Thousands of kinds of laser are known, but most of them are used only for specialized research.
Lasers used in medicine include, in principle, any type of laser, but especially the following: CO 2 lasers, used to cut, vaporize, ablate, and photocoagulate soft tissue. diode lasers; dye lasers; excimer lasers; fiber lasers; gas lasers; free electron lasers; semiconductor diode lasers; Applications in medicine
Lasers have many uses in medicine, including laser surgery (particularly eye surgery), laser healing (photobiomodulation therapy), kidney stone treatment, ophthalmoscopy, and cosmetic skin treatments such as acne treatment, cellulite and striae reduction, and hair removal.
Burn and surgical scar management: scar contracture CO 2 (especially the newer fractionated CO 2 lasers), redness and itch (Pulsed Dye laser - PDL), post-inflammatory hyper-pigmentation (Q-switched lasers :Ruby, Alexandrite), burn scar unwanted hair growth and trapped hairs (Ruby, IPL and numerous hair removal lasers)
Because lasers can focus very accurately on tiny areas, they can be used for very precise surgical work or for cutting through tissue (in place of a scalpel). Three types of lasers are used to treat cancer: carbon dioxide (CO 2) lasers, argon lasers, and neodymium:yttrium-aluminum-garnet lasers.
