Abstract
For increasing the laser damage threshold (LDT) of diffraction gratings, particularly of multi-layer dielectric diffraction (MLD) gratings, the invention proposes a method for treating a diffraction grating to be used in a high energy laser apparatus having a first laser with the steps of providing the diffraction grating, providing a second treatment laser and irradiating the diffraction grating with laser light from the second treatment laser until the laser damage threshold of the diffraction grating has increased. Furthermore, the invention proposes a diffraction grating treated according to the method, as well as a laser system, which comprises such a diffraction grating.
