  • Method for the laser machining of a workpiece
    Patent number: 12285821
    Abstract: A method for the laser machining of a workpiece by using a machining beam is provided. Material modifications are formed in the material along a predetermined machining line by action of the machining beam upon the material. A first group of spaced-apart material modifications is formed in the material, with adjacent material modifications of the first group being formed one after the other in time and having a distance d0 from one another of at least 0.25*? and/or at most 2.5*?. A second group of spaced-apart material modifications is formed in the material, with mutually material modifications of the second group being formed one after the other in time and having a distance d0 from one another of at least 0.25*? and/or at most 2.5*?. The shortest distance d1 between the material modifications of the first group and the material modifications of the second group being at least 5 ?m.
