Patent number: 10386631Abstract: A laser beam machining device having a laser beam source and an equipment for deflecting a laser beam of the laser beam source for machining a workpiece is provided. The equipment includes a mounting body, a structural member having a reflecting surface, a flexible element by which the structural member is deflectable around an arbitrary space axis about an angle of deflection, a first forcing component and at least one second forcing component, whereby at least one of the forcing components are controllable such that the two forcing components are attracted towards each other or repel each other depending on the triggering. One of the forcing components is coupled to the structural member and the two forcing components are arranged and cooperate such that the structural member deflects around the arbitrary space axis about a predetermine angle of deflection.Type: GrantFiled: March 13, 2015Date of Patent: August 20, 2019Assignee: TRUMPF Schweiz AGInventors: Carsten Ziolek, Stefan Marzenell

Patent number: 9823435Abstract: A device for moving a nonlinear crystal or a saturable absorber in two dimensions includes a first and a second piezo unit, each having a corresponding carrier, piezo driver, and carriage moveable by the piezo driver at incremental steps along a linear path with respect to the carrier between a first and a second end location, in which the linear paths of the first piezo unit and the second piezo unit are orthogonal. The nonlinear crystal/saturable absorber is fastenable on the carriage of the first piezo unit and the carrier of the first piezo unit is fastened on the carriage of the second piezo unit. The device further includes stops that define the carriage end locations, an end location detection configured to detect the carriages at their respective end locations, and a counting unit configured to count the steps covered during the moving of the carriage.Type: GrantFiled: August 2, 2016Date of Patent: November 21, 2017Assignee: Trumpf Laser Marking Systems AGInventors: Carsten Ziolek, Dirk Bueche, Thomas Huerlimann, Erich Sprecher, Nikolaus Willi

Patent number: 8553734Abstract: A system includes: a first nonlinear crystal arranged to receive to a first laser beam having a first wavelength ?1 and operable to generate, by frequency doubling of the first laser beam, a second laser beam having a second wavelength ?2, in which the second beam propagates collinearly with the first beam; a second nonlinear crystal arranged to receive the first and second laser beams from the first crystal, in which the second crystal is operable to generate, by frequency mixing of the first and second laser beams, a third laser beam having a third wavelength ?3; and one or more lenses between the first and second crystals, in which the one or more lenses are operable to spatially separate the first and second beams. The first and second laser beams propagate at an offset and/or titled with respect to an optical axis in order to cause the spatial separation.Type: GrantFiled: October 1, 2012Date of Patent: October 8, 2013Assignee: Trumpf Laser Marking Systems AGInventors: Shalei Dong, Sven Joosten, Carsten Ziolek
