Abstract
A method is provided for producing a glass ceramic element with a patterned coating is provided. The method includes: providing a glass ceramic element with a coating which is at least partially light-blocking and preferably opaque in the visible spectral range; irradiating the glass ceramic element with a pulsed laser beam on the face provided with the coating so that the coating is removed by ablation; during irradiating the laser beam is directed over the surface of the glass ceramic element so that a portion of the coating is removed which has a greater lateral extent than the diameter of the laser beam; and once the coating has been removed, irradiating the glass ceramic with the laser in the region where the coating has been removed, thereby optically modifying the glass ceramic in the irradiated region.
