  • Determining a focal position of a laser
    Patent number: 8304691
    Abstract: A method is performed for determining a suitable workpiece processing focal position of a laser beam. The method includes adjusting one or more of a laser beam and a workpiece until a periphery of the laser beam contacts a lateral edge of the workpiece, determining, from at least a focal position of the laser beam associated with the peripheral beam contact with the workpiece, a suitable workpiece processing focal position of the laser beam, and then adjusting the laser beam to the suitable workpiece processing focal position.
    Type: Grant

    Inventors: Wolfgang Scholich-Tessmann, Andreas Milich
  • Ascertaining a laser beam contact point
    Patent number: 8258430
    Abstract: A method of determining a contact point of a laser beam on an edge of a body and a system for performing the same, in which the method includes a) moving the laser beam relative to the edge in a spatial direction until the laser beam touches the edge, in which the spatial direction is at a right angle relative to an axis of the laser beam and in which the edge is formed at an opening, b) measuring acoustic oscillations produced photoacoustically during the movement of the laser beam, and c) determining the laser beam point of contact with the edge based on the measured acoustic oscillations.
