First, there are uncertainties about the fun- damental molecular and cellular mechanisms responsible for transducing signals from the photons incident on the cells to the biological effects that take place in the irradiated tissue. LED was suggested as a treatment modality for facilitating faster healing. The shorter wavelengths are the ultraviolet and the longer wavelengths are the infrared.

It provides for a great semantic argument, but assume at this point that therms are generally interchangeable. The peak visibility describes the prominence of Raman bands above the noise level in the background. If you make use of the information, please acknowledge its source. Introduction Human skin is the interface between man and his environment. Published online Sep Diode lasers for various surgical procedures including soft tissue cutting, coagulation and cancer thermal therapy using various photosensitizers matching the laser absorption wavelengths .
From Wikipedia, the free encyclopedia. YAG laser treatment is associated with higher pain scores and a higher risk of postinflammatory hyperpigmentation . It is the expansion of this shock wave which causes the destructive effect. The study examined the tissue absorption profile combined with Raman scattering and detection sensitivity at seven different, laser excitation wavelengths in the near infrared region of the spectrum. Red light penetrates deeper than blue light [ 1 ].
The lasers used to treat vascular lesions have wavelengths that are well absorbed by hemoglobin. If exactly the same amount of energy left the tissues which was introduced into them, it is difficult to rationalise what kind of effect might have been achieved. If light rays strike a mirror, almost all of the energy incident on the mirror will be reflected. The IPL wavelength window is about to 1, nm. Also readily noticeable is the absence of the double peaks for the nm excitation when the vial is situated in front of the tissue on the illumination side. Depending on laser power and beam spot needed, commercially available fibers have typical size core of um, and length of 1.
