  • Publication number: 20100116797
    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.

  • Publication number: 20090001063
    Abstract: A laser processing machine includes a laser that outputs a laser beam, a laser processing head including a nozzle that defines a nozzle bore, a beam guidance and focusing system for directing the laser beam through the nozzle bore of the laser processing head, an illumination system that produces a light beam that is directed at the nozzle bore of the nozzle such that the light beam completely illuminates the nozzle bore, a light detector at the nozzle bore that views light that exits the nozzle bore, and an evaluation system that receives the output of the light detector and automatically determines the separation between a center of the laser beam when the laser beam is focused at the nozzle and a center of the nozzle based on the light detector output.

  • Publication number: 20080088924
    Abstract: An optical module adjusts an output of a laser of a laser processing machine. The optical module consists essentially of an adaptive spherical mirror configured to receive a laser beam from the laser, and a spherical mirror configured to receive a laser beam reflected from the adaptive mirror. Both the adaptive mirror and the spherical mirror have a phase-shifting coating such that the laser beam reflected from the spherical mirror has a circular polarization.

  • Publication number: 20070291379
    Abstract: A laser processing machine head, a laser processing machine head monitoring system, and a method of monitoring an optical element of a laser processing machine feature a light-transmissive optical element and an optical element holder defining a cavity in which the optical element is retained against rotation. A light source mounted to the holder directs a beam of light into the optical element through a peripheral surface of the optical element. A light receiver is responsive to light from the light source reflected through the optical element. Monitoring a signal from the light receiver allows a status of the optical element to be assessed.

  • Publication number: 20060027537
    Abstract: A laser processing head includes a first housing region associated with a beam guidance of a laser processing machine, a second housing region associated with the laser processing head, and an aperture in a wall separating the first and second housing regions. The head is configured such that a laser beam may pass sequentially through the beam guidance, the first housing region, the aperture, and the second housing, and the first housing region includes a first gas atmosphere associated with the beam guidance and maintained at a higher pressure than a second gas atmosphere in the second housing region.

  • Publication number: 20040094525
    Abstract: A laser processing machine includes a measuring cell into which gas to be analyzed can flow, a means for decoupling diagnostic radiation from the laser radiation provided for material processing of a workpiece, and a sound detector for detecting the photo-acoustical effect produced in the measuring cell due to absorption of the diagnostic radiation by gas in the cell.

  • Patent number: 6018135
    Abstract: A laser processing machine has a laser beam generator (2), a processing head (4) movable relative thereto, and a gas chamber (10) connected to a gas compensating chamber (15). The gas chamber (10) provides at least part of the beam guidance chamber (6) for the laser beam (5), and at least partially is bordered by a expansible and compressible gas chamber wall (11, 12) which expands and compresses with the motion of the processing head (4) relative to the laser beam generator (2). The guidance gas chamber (10) is essentially closed apart from the flow connection to the gas compensating chamber (15), and the gas compensating chamber (15) changed in size response to the expansion and compression of the gas chamber wall (11, 12).

  • Patent number: 5811753
    Abstract: A laser machine tool includes a laser beam generator (3) and a machining head (5), and the laser beam (2) passes between the laser beam generator (3) and the machining head (5) in a beam passage (25) that is at least partially closed. The beam passage (4) is filled with air with a limited CO.sub.2 content. In this way, the laser beam (2) in the beam passage is protected at low cost from the influence of gases that reduce its power, especially when the path of the beam is very long.

  • Patent number: 5667707
    Abstract: On laser cutting machines the laser cutting head is movable relative to the laser generator, respectively relative to the workpiece to be cut, in a plane parallel to the workpiece by means of a drive controlled by a numerical control. The laser cutting head also has an adjusting device for adjusting the focal position of the laser beam, by means of which the focus can be shifted with respect to the laser cutting head perpendicular to the workpiece. The position of the laser beam focus perpendicular to the workpiece influences the cutting quality obtained, respectively the resulting cutting characteristics. A laser cutting machine which is functionally efficient under workshop conditions and suitable for automatic operation, for which a sure optical adjustment of the focal position is possible, has not been available up to now. The new laser cutting machine should eliminate this problem.
