  • Method and device for laser drilling in a process gas atmosphere
    Patent number: 7301121
    Abstract: A method and device for laser drilling in which the geometric form of the drill-hole wall is influenced by reciprocal action between a laser beam and a supplied process gas, which thereby is ionized to plasma. Furthermore, the outlet opening of the drill hole is influenced by a suitable arrangement of a backing.
    Type: Grant
    Filed: November 17, 2003
    Date of Patent: November 27, 2007
    Assignee: Robert Bosch GmbH
    Inventors: Gert Callies, Markus Willert, Kai Osswald
  • Method and device for drilling holes in workpieces by means of laser beams
    Patent number: 7294807
    Abstract: A method and a device for producing holes in workpieces by using at least one laser beam, in particular a short-pulse or ultrashort-pulse laser beam, whereby a process gas is supplied to the point of contact of the laser beam with the workpiece. At least one parameter of the process gas, i.e., its composition, pressure, volume flow, for example, is selected and the process gas is supplied to the interaction zone between the laser beam and the workpiece in such a way that the hole produced by the laser beam has a desired quality (hole geometry, reduced ablation residues, or none at all, etc.).
