Eye surgery. Various types of laser surgery are used to treat refractive error. LASIK, in which a knife is used to cut a flap in the cornea, and a laser is used to reshape the layers underneath, is used to treat refractive error. IntraLASIK is a variant in which the flap is also cut with a laser.
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, [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. free electron 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 .
Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates.
Nd: YAG lasers are optically pumped using a flashtube or laser diodes. These are one of the most common types of laser, and are used for many different applications. Nd:YAG lasers typically emit light with a wavelength of 1064 nm, in the infrared. [3] However, there are also transitions near 946, 1120, 1320, and 1440 nm.
