Patent number: 10133024Abstract: An optical element holding device adjusts an optical element about a first and second axis and includes a main support, and a first plate-shaped support mounted on the main support via a first flexure bearing. The first support can pivot about the first axis. A second support is mounted on the first support via a second flexure bearing and can pivot about the second axis and fasten to the optical element. A first and second actuating element are actuated from a same side of the optical element holding device. A transmission device connected to the first and the second supports transmits the second actuating element movement acting on the transmission device into a pivoting movement of the second support about the second axis. The pivoting positions of the first and second supports can be set by the actuating elements and the second axis is oriented substantially perpendicularly to the plate-shaped first support.Type: GrantFiled: April 15, 2016Date of Patent: November 20, 2018Assignee: TRUMPF LASER GMBHInventors: Martin Liermann, Manuel Wolf, Jochen Doerner, Sarah Hilarius, Walter de Wall

Patent number: 7936799Abstract: A laser system includes at least two sources configured to provide at least two spatially separated laser beams, and a mount configured to mount the at least two sources along an arc, the arc defining an angular coordinate and a radial coordinate, wherein an axial coordinate is orthogonal to the angular coordinate and the radial coordinate, and the spatially separated laser beams are separated in the axial coordinate. The mount is further configured to mount the at least two sources providing thereby an offset of the laser beams in the axial coordinate such that the laser beams interleave in the axial direction at a center region of the arc.Type: GrantFiled: October 27, 2008Date of Patent: May 3, 2011Assignee: Trumpf Photonics Inc.Inventors: Ulrich Bonna, Martin Liermann, Viorel C. Negoita, Thilo Vethake, Alexander Killi, Christoph Tillkorn

Patent number: 7167312Abstract: A beam shaping optical arrangement combines three incoming laser beams that are mutually laterally offset in two orthogonal directions (X and Y), including an incoming first central laser beam and second and third incoming beams laterally offset in the X direction on either side of the central beam, into one outgoing combined laser beam. The arrangement includes two lateral displacement optical units though which the laterally offset incoming beams are transmitted and that laterally displace the two laterally offset incoming beams along the X direction towards the incoming central beam but which do not laterally offset the incoming central beam.Type: GrantFiled: May 27, 2005Date of Patent: January 23, 2007Assignee: Trumpf Laser GmbH + Co. KGInventors: Andreas Voss, Martin Huonker, Martin Liermann, Klaus Wallmeroth, Malte Kumkar, Friedheim Dorsch, Christian Schmitz
