Abstract
A method for microstructuring a plate-shaped glass substrate by laser radiation includes: introducing one-sided recesses into the glass substrate, in which a focus of the laser radiation forms a spatial beam along a beam axis and in which the laser radiation creates modifications in the glass substrate along the beam axis so that an action of an etching medium subsequently creates the recesses in the glass substrate through anisotropic removal of material in a respective region of the modifications. A chemical composition of the glass substrate is partially changed and thus at least one region of changed properties is created before the action of the etching medium.
