Author: Anoma Ranaweera B. July Introduction - laser Introduction How it works Uses. LASER s light amplification by stimulated emission of radiation are sources of high-intensity monochromatic single wave length coherent light that can be used for the treatment of various dermatologic conditions.
How they are used depends on the wavelength, pulse characteristics, and fluence energy output of the laser being used, and the nature of the condition being treated. Various kinds of lasers are available; they are differentiated by the medium that produces the laser beam.
Each of the different types of lasers has a specific range of utility, depending on its wavelength and penetration. A ruby laser is a solid -state laser that uses a synthetic ruby crystal as its laser medium. The wavelength of a laser is measured in namometres nm. Ruby lasers produce pulses of visible light of a deep red colour, at a wavelength of Typical ruby laser pulse lengths are of the order of a millisecond.
Melasma is an acquired pigmentary disorder characterised by brownish hyperpigmented macules that usually appear on the face. The role of ruby laser in melasma treatment is controversial, as studies showing conflicting results. It is important that the correct diagnosis has been made by the clinician prior to treatment, particularly when pigmented lesions are targeted to avoid mistreatment of skin cancer such as melanoma.
The patient should wear eye protection consisting of an opaque covering or goggles throughout the treatment session. Main menu. Topics A-Z. Skin checker. Give feedback.
