Laser radiation being delivered via a fiber for photodynamic therapy to treat cancer. A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery.
Laser surgery is a type of surgery that cuts tissue using a laser in contrast to using a scalpel. [ 1 ] Soft-tissue laser surgery is used in a variety of applications in humans ( general surgery , neurosurgery , ENT , dentistry , orthodontics , [ 2 ] and oral and maxillofacial surgery ) as well as veterinary [ 3 ] surgical fields.
The back-formed verb "to lase" is frequently used in the field, meaning "to give off coherent light," especially about the gain medium of a laser; [16] when a laser is operating, it is said to be "lasing". [17] The terms laser and maser are also used for naturally occurring coherent emissions, as in astrophysical maser and atom laser. [18] [19]
The following terms are accepted as alternatives of low level light therapy term: LLLT, laser biostimulation, laser phototherapy, low-level laser therapy, low-power laser irradiation, low-power laser therapy, and photobiomodulation therapy. The term photobiomodulation therapy is considered the preferred term by industry professionals.
Medical optical imaging is the use of light as an investigational imaging technique for medical applications, pioneered by American Physical Chemist Britton Chance.Examples include optical microscopy, spectroscopy, endoscopy, scanning laser ophthalmoscopy, laser Doppler imaging, optical coherence tomography, and transdermal optical imaging.
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 .

Laser-assisted new attachment procedure (LANAP) is a surgical therapy for the treatment of periodontitis, intended to work through regeneration rather than resection. This therapy and the laser used to perform it have been in use since 1994. [citation needed] It was developed by Robert H. Gregg II [1] [2] and Delwin McCarthy.
