laser

 [la´zer]
a device that transfers light of various frequencies into an extremely intense, small, and nearly nondivergent beam of monochromatic radiation in the visible or invisible spectrum, with all the waves in phase; capable of mobilizing immense heat and power when focused at close range, lasers act on tissues by photocoagulation and photodisruption and are used in surgery, in diagnosis, and in physiological studies.
argon laser a laser with ionized argon as the active medium and with a beam in the blue and green visible light spectrum; used for photocoagulation.
carbon-dioxide laser a laser with carbon dioxide gas as the active medium and that produces infrared radiation at 10,600 nm; used to excise and incise tissue and to vaporize.
excimer laser (excited dimer) a laser with rare gas halides as the active medium, used in ophthalmological procedures and angioplasty. The beam is in the ultraviolet spectrum and penetrates tissues only a small distance; it breaks chemical bonds instead of generating heat to destroy tissue.
holmium: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.
neodymium: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 approximately 1060 nm; used for photocoagulation and photoablation.

argon laser

laser used for ophthalmic procedures, including retinal photocoagulation and trabeculoplasty, consisting of photons in the blue (488 nm) or green (514 nm) spectrum.

Laser used for ophthalmic procedures, including retinal photocoagulation and trabeculoplasty, consisting of photons in the blue (488 nm) or green (514 nm) spectrum.

argon laser

A low-powered LASER widely used in ophthalmology.

laser

a device which generates an extremely intense, small and nearly nondivergent beam of monochromatic radiation in the visible region, with all the waves in phase; capable of mobilizing immense heat and power when focused at close range, it is used as a tool in surgery, in diagnosis, and in physiological studies. Laser is an acronym for light amplification by stimulated emission of radiation.
Used also as a modern version of acupuncture and considered to be the biggest breakthrough in that technology for 5000 years. It provides a quick, painless and noninvasive method of point stimulation.

argon laser
used in ophthalmic surgery and in photodynamic surgery of the skin.
carbon dioxide laser
used in microsurgery and ophthalmic procedures.
low-energy laser therapy
used for wound healing and pain relief; includes visible red helium-neon lasers, invisible infrared gallium-arsenide lasers and gallium-aluminum-arsenid lasers.
laser therapy
in acupuncture the application of low intensity laser to acupuncture points.
