Method for the laser ablation of brittle components in preparation for the subsequent separation of the same, by the introduction of sack-like indentations by a laser beam, wherein the indentations are arranged in a line one after the other, and form a laser ablation line which serves as the fracture initiation line, wherein the term laser ablation line means a line formed by connecting the middle points of all the indentations. At least two laser ablation lines are introduced onto the component surface and cross each other at a cross point. In order to ensure that the fracture always runs along the laser ablation line during the separation process, that fractures deviating from the laser ablation line are avoided, and that the corners of the separated pieces following fracturing are evenly shaped, it is suggested according to the invention that at least one cross point indentation is introduced at the cross point in a targeted, controlled, and intentional manner, which specifically weakens the component at the cross point.
