  • Device and method for laser material machining
    Patent number: 9616522
    Abstract: The invention discloses a device for laser material machining, with at least two laser beam sources (2a-2c) which emit laser beams (5a-5c) of different wavelengths, with associated beam imaging means (3a-3c), to configure appropriately the beam paths of each associated laser beam (5a-5c), a beam superposition device (6), to overlay the laser beams (5a-5c) on each other, and imaging optics (8), to image the overlaid laser beams (5a-5c) onto a workpiece (12) so that respective focal points are associated with the laser beams (5a-5c) in the focus of the imaging optics (8) on the workpiece (12), wherein the beam imaging means image the laser beams (5a-5c) onto the respective focal points in a predefined arrangement which can be varied by means of the beam imaging means (3a-3c).
