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 dfrom one another of at least 0.25*λ and/or at most 2.5*λ. 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 dfrom one another of at least 0.25*λ and/or at most 2.5*λ. The shortest distance dbetween the material modifications of the first group and the material modifications of the second group being at least 5 μm.
