Beschreibung
Zusammenfassung:	A method of treating a surface for the removal of a surface portion is described comprising the steps of: irradiating the surface with laser light characterised in that the irradiation is effected by covering said surface in a sequential manner with a plurality of discrete spots of laser light. The spots of laser light overlap and may be arranged in a geometric arrangement defined by the locations of the centres of the spots of laser light. The spots of laser light may be applied sequentially. L'invention concerne un procédé de traitement de surface destiné à éliminer une partie de la surface, ledit procédé comprenant les étapes suivantes : irradier la surface au moyen d'un laser, caractérisé en ce que l'irradiation est effectuée par le recouvrement de ladite surface d'une manière séquentielle au moyen d'une pluralité de points discrets de laser. Les points de laser s'imbriquent les uns les autres et peuvent être disposés dans une configuration géométrique, laquelle est définie par les emplacements des centres des points de laser. Les points de laser peuvent être appliqués de manière séquentielle.
