During laser irradiation of biological tissue several steps have to be considered: (a) propagation of light in tissue including reflection and scattering, (b) transformation of laser light into photochemical, acoustic, or thermal energy, depending primarily on the absorber, pulse energy, and pulse duration, (c) propagation of the spatial temperature profile for the fraction of light energy that was transformed into thermal energy, and propagation of acoustic transients for the fraction of light energy that was converted into mechanical energy, and (d) the dependency between temperature elevation and tissue damage, which can be described by the Arrhenius law.
