Abstract: The present application relates to a device for the mask projection of femtosecond or picosecond laser beams (2) onto a substrate surface, in which the laser beam (2) consisting of laser beam pulses is, at a location of the optical axis, formed to make laser beam pulses with an expanded laser beam cross section or laser beam pulses with a reduced laser beam cross section and said laser beam (2) has a homogeneous intensity distribution over the laser beam cross section. A stop (6) with a predetermined stop aperture geometry and a mask (7) with a predetermined mask aperture geometry are positioned in succession in the beam (2) path at the location.

Abstract: In the method for structuring at least one area of a solid body surface provided with a ta-C coating, by means of a first laser, preferably an excimer laser having pulse durations in the nanosecond range, a first structure is produced upon which a second, ripple-like structure is superposed by means of a second laser, preferably having pulse durations in the femtosecond range. Preferentially, the excimer laser structuring is carried out according to the mask projection technique and the femtosecond laser structuring according to the focus technique. This method allows the rational manufacture of very complex, extremely fraud-resistant authentication features and/or of esthetically attractive, optical diffraction effective colored patterns.

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.

Abstract: In the method for structuring at least one area of a solid body surface provided with a ta-C coating, a mask in the homogenous spot of the optical system is used in order to shape the beam in the mask projection technique and then a diaphragm in front of the imaging optics. A structure is applied by means of an excimer laser having pulse durations in the nanosecond range, a number of mask and diaphragm combinations being arranged in a exchanger device and the exchanger device being adapted to place both one of the masks and one of the diaphragms in the beam path of the laser independently of each other, the masks and diaphragms being arranged in holders while being displaceable linearly or rotatively and rotatable about themselves. This method allows the rational manufacture of very complex, extremely fraud-resistant authentication features and/or of esthetically attractive, optical diffraction effective colored patterns.
