Abstract:
1. A method for incorporating a structure into a surface of a workpiece which is transparent at a specific wavelength range, comprising: providing a target material having a target surface; bringing a surface to be structured of the workpiece into contact with the target surface of the target material, providing a laser beam having a wavelength range, the laser beam having a focus with a power density of more than 2000 W/mm focusing the laser beam on or below the target surface, and shooting the laser beam through the workpiece and into a boundary region of the surface to be structured of the workpiece and the target surface at least at one position to cause the target material to be deposited in the surface to be structured of the workpiece, wherein shooting the laser beam is performed with a pulse repetition rate of more than 10 kHz.
