Abstract
The aim of this work was to evaluate the temperature fi elds and the dynamics of heat conduction into the skin tissue under several laser irradiation conditions with both a pulsed ultraviolet (UV) laser (λ=337 nm) and a continuous-wave (cw) visible laser beam (λ=632.8 nm) using Monte Carlo modeling. Finite-element methodology was used for heat transfer simulation. Th e analysis of the results showed that heat is not localized on the surface, but is collected inside the tissue in lower skin layers. Th e simulation was made with the pulsed UV laser beam (used as excitation source in laser-induced fl uorescence) and the cw visible laser (used in photodynamic therapy treatments), in order to study the possible thermal eff ects.
