Abstract
In the method for producing masks and/or diaphragms for a laser installation for the creation of microstructures on a solid body surface according to the mask projection technique, predetermined opaque surface portions which scatter the laser radiation are produced in the mask and/or diaphragm substrate by roughening and modifying the latter by means of a femtosecond, picosecond or fluor laser beam. Such masks and diaphragms have a strongly improved lifetime and accuracy and may e.g. serve for the creation of blazed gratings which, arranged in diffraction grating arrays on a solid body surface, serve for producing spectral colors and mixed colors of high brilliance.
