Abstract:
1. A method for structuring at least one area of an exposed surface of a hard material coated on a solid body, comprising: passing a homogeneous intensity distribution spot of a laser beam having laser pulse durations in a nano-second range through a mask and a diaphragm before imaging the laser beam on said at least one area using imaging optics positioned downstream of the mask and diaphragm, wherein the hard material comprises an amorphous carbon having a fraction of more than 50% of diamond-like sp wherein during the structuring produced by the nanosecond laser on the workpiece surface in the passing step, structures obtained are measured by means of a diffractometer and the measured values are used for adjusting an intensity of the laser beam and/or the imaging optics and a focusing optic.
