Abstract
A method for the ablative reshaping of material surfaces, including the steps of providing a source of an ablative beam having a given average fluence distribution over its cross-sectional extent, determining the ablation curve of the material to be reshaped, selecting, from said ablation curve, an ascending region having an at least approximately constant slope, selecting a beam fluence from among the fluences comprised in said region, irradiating the material surface to be shaped, and controlling the geometry of the material surface thus being reshaped by controlling the total amount of energy per unit area of said surface delivered during said irradiation.
