Abstract
The photoablation process of soft tissue with free-running infrared la sers (lambda = 2.70 mu m, 2.79 mu m, 2.94 mu m) is not well understood , in particular for temperature-dependent absorption. An evaporation m odel has been developed, solved by the finite-element method and compa red with experimental results. Both, the ablation rates and the therma l damages can be explained by a pure vaporization process with huge in fluence of the temperature-dependent absorption.
