Abstract
We present a theory of thermal laser ablation based on the heat equation and on an energy balance equation derived from it. Ablation is assumed to be brought about by the heating and evaporation of tissue water. The model is three‐dimensional, and scattering and the water‐steam phase transition are explicitly taken into account. The model predicts threshold parameters and a steady‐state ablation velocity in terms of the optical and thermal properties of the tissue and the laser beam intensity and spot diameter.Keywords
