Patent number: 9638907Abstract: Methods and devices for expanding a laser beam are provided. In one aspect, a device includes a telescope arrangement having two spherical folding mirrors for expanding an incident collimated laser beam with a lens arranged in the divergent beam path downstream of the telescopic arrangement. The two spherical folding mirrors in the beam path are a first, convex-curved spherical folding mirror and a second, concave-curved spherical folding mirror, respectively. The lens has a spherical lens face for collimating the expanded laser beam from the telescope arrangement. The laser beam can be an ultraviolet (UV) laser beam.Type: GrantFiled: March 15, 2012Date of Patent: May 2, 2017Assignee: TRUMPF LASER GMBHInventors: Klaus Wallmeroth, Christoph Tillkorn, Ivo Zawischa

Patent number: 7428257Abstract: An apparatus for optically pumping a laser-active solid body with pumping light coupled into the solid body through an end surface of the solid body is disclosed. The apparatus includes a laser-active solid body including an end surface though which pumping light is coupled into the solid body and a lateral surface through which pumping light exits the solid body, a reflector surrounding the laser-active solid body at a distance from the lateral surface of the solid body for reflecting light that exists the solid body back towards the solid body, and a surface for diffusing light that is coupled into the solid body through the end surface of the solid body and that exits the solid body through the lateral surface. The surface is selected from the group consisting of the lateral surface and a surface of the reflector.Type: GrantFiled: January 28, 2004Date of Patent: September 23, 2008Assignees: Trumpf Laser GmbH + Co. KG, Trumpf Laser Marketing Systems AGInventors: Malte Kumkar, Shalei Dong, Klaus Wallmeroth, Andreas Oehler, Karla Nate, legal representative, Wolfgang Nate, legal representative, Markus Nate

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.
