  • Device for and method of establishing joints by means of laser beams
    Patent number: 4912297
    Abstract: In a device for joining by means of laser radiation, in particular for welding edges, the laser beam travels essentially parallel to the plane of the joint gap and is directed essentially perpendicular to the joint line. To ensure that the energy of the laser radiation is absorbed almost entirely in the region of the joint, the laser radiation is polarized mainly parallel to the plane of the joint gap and/or the laser beam (20) is shaped or focused at right angles to the joint gap (12) in the form of a strip parallel to said gap.

  • Arrangement for machining workpieces by means of a laser beam by building up a plasma that is to be kept within limits
    Patent number: 4839493
    Abstract: In machining a workpiece, maximal absorption of laser irradiation in the workpiece is achieved by a minimal interference by optical back-coupling and plasma effects is achieved by continuously determining the actual value of the laser irradiation and continuously sensing stochastic processes taking place in the machining zone and in response to such measuring and sensing, controlling the modulation of laser irradiation.
