Laser

Acronym for light amplification by stimulated emission of radiation. A technique that converts light from several frequencies into an intense, visible, small, non-divergent, monochromatic radiation beam that is capable of creating immense localized heat and power when concentrated and directed at a short distance.

An instrument for producing an enormously intense and sharply directed beam of light.

An instrument which produces a highly concentrated beam of light which can be used to cut or attach tissue, as in operations for a detached retina.

Acronym for Light Amplification by Stimulated Emission of Radiation; an instrument that produces a very thin beam or light—of one wavelength—with radiation intense enough to be used surgically to destroy tissue or to separate parts.

A high-intensity light source used to excise tissue, thereby avoiding more traumatic surgical procedures.

A medical instrument that produces a very thin, powerful beam of light. The term “laser” stands for light amplification by stimulated emission of radiation. There are several types of lasers, each of which has a specific use. The color of the laser used is directly related to the surgery being performed and to the tissue being treated.

A device that produces a very thin beam of light in which high energies are concentrated. In surgery lasers can be used to operate on small areas of abnormality without damaging delicate surrounding tissue.

A device that emits intense energy and heat by converting light of a spectrum of frequencies into light of a single frequency (wavelength) in a narrow, focused beam. The term comes from Light Amplification by Stimulated Emission of Radiation.

This stands for Light Amplification by Stimulated Emission of Radiation. The light produced by a laser is of a single wavelength and all the waves are in phase with each other, allowing a very high level of energy to be projected as a parallel beam or focused on to a small spot.

Acronym for light amplification by stimulated emission of radiation. It is a device that emits intense heat and power at close range. The instrument converts various frequencies of light into one small, extremely intense unified beam of a single frequency or wavelength radiation. The laser can be focused on a very small target. Lasers can be used surgically in a wide variety of ways. They influence cellular chemistry (the “photochemical” effects of lasers). They damage tissues by generating heat (e.g., producing coagulation, the “photothermal” effects). They can drill into, cavitate, or explode tissues (“photomechanical” effects). They can ablate tissues after transforming them into plasma. In addition to their surgical uses, lasers can be used for diagnosis (e.g., by illuminating cells or tissues, as in fluorescence); and they have a vast number of laboratory applications. Lasers have many treatment applications. In ophthalmology, they are used in treating cataracts, diabetic retinopathy, macular degeneration, and retinal detachment; in cardiology, to vaporize arterial obstructions; in dermatology, to obliterate blood vessels and to remove warts, skin cancers, nevi, excess tissue, and tattoos; in gynecology, to remove vulval lesions, including genital warts; in gastroenterology, to control bleeding in the gastrointestinal tract; and in oral surgery and dentistry, to remove tumors. Many kinds of lasers are used depending upon the wavelength and power required, including argon, carbon dioxide, copper vapor, dye, excimer, helium-neon, ion, krypton, neodymium: yttrium-aluminum garnet, and ruby lasers.

Acronym for light amplification stimulation emission of radiation; a medical device that uses electromagnetic radiation for hair removal and skin treatments.

A device designed to emit electromagnetic radiation at precise wavelengths, typically within the ultraviolet, visible, or infrared regions of the spectrum, is commonly known as a radiating apparatus. This sophisticated device is engineered to generate and release electromagnetic waves, facilitating a diverse range of applications across various fields, including scientific research, telecommunications, imaging, and many others. By operating at specific wavelengths, these devices enable targeted interactions with matter, leading to numerous practical and technological advancements.
