Skin-light interaction of three main chromofores in skin affected by Port Wine Stain

In this paper, simulation and mathematical analysis of the absorption, dispersion and dynamics of laser light generated at 690nm and its interaction with skin affected by the Port Wine Stain is presented. The absorption coefficient and penetration depth of water, hemoglobin and oxy-hemoglobin, as key chromophores are calculated. A suitable wavelength for possible treatment on Port Wine Stain located in the skin layers such as Dermis and Hypodermis is determined. The presentation will include a full fiber laser design description, detailed skin affectation explanation and preliminary results.
