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. Lasers used in medicine include, in principle, any type of laser, but especially the following: CO 2 lasers, [12] used to cut, vaporize, ablate, and photocoagulate soft tissue. [13] diode lasers [14] dye lasers [1] [15] excimer lasers. fiber lasers [16] gas lasers.
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.
There are several laser types used in medicine for ablation, including argon, carbon dioxide (CO 2), dye, erbium, excimer, Nd:YAG, and others. Laser ablation is used in a variety of medical specialties including ophthalmology, general surgery, neurosurgery, ENT, dentistry, oral and maxillofacial surgery, and veterinary.
Laser-Assisted in Situ Keratomileusis (LASIK), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and an actual cure for astigmatism, since it is in the cornea.
Lasers. Pulsed dye lasers have been used with fiber diameters of 200–550 microns for lithotripsy of biliary and urinary stones. Ho:YAG lasers have wavelength of 2100 nm (infrared) and are used for medical procedures in urology and other areas. They have qualities of CO 2 and Nd:Yag lasers, with ablative and coagulation effects.
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.
Laser resurfacing is a laser surgery technique that disassociates molecular bonds. It is used for the treatment of wrinkles, solar lentigenes , sun damage , scarring ( acne scars and surgical scars), stretch marks , actinic keratosis , and telangiectasias .
A helium–neon laser or He-Ne laser is a type of gas laser whose high energetic medium gain medium consists of a mixture of ratio (between 5:1 and 20:1) of helium and neon at a total pressure of approximately 1 Torr (133 Pa) inside a small electrical discharge. The best-known and most widely used He-Ne laser operates at a wavelength of 632.8 ...
