Paper Abstract

We have studied dynamic changes in optical properties of various tissues during argon and pulse Nd:YAG laser irradiation while monitoring tissue surface temperature. High power laser radiation induces reversible and/or irreversible changes in the optical behavior of the tissue. Reversible changes in diffuse reflectance and total transmittance can be as much as 15% and 20% of initial values, respectively. We are currently investigating the mechanism responsible for the observed reversible changes.
