The invention relates to a method for incorporating a structure into a surface of a workpiece that is transparent in a certain wavelength range. For this purpose the surface to be structured is brought into contact with a target surface containing a target material by means of a laser beam, the wavelength of which is within the certain wavelength range, energy is introduced at least at one position through the workpiece and into the boundary region of the surface to be structured and the target surface such that target material is deposited at the respective position in and/or on the surface to be structured. For this purpose a pulsed laser beam having a pulse repetition rate of more than 10 kHz is used, which is focused such that the focus is positioned on or under the target surface, wherein the laser beam has a power density in the focus of more than 2000 W/mm2. The invention further relates to a device for introducing a structure into a surface of a workpiece transparent in a certain wavelength range. |
