Patent number: 8817833Abstract: A gas laser includes discharge tubes connected to together by corner housings, each corner housing including a first cooling channel configured to allow flow of a first coolant. A heat exchanger circuit includes a plurality of second cooling channels configured to allow flow of a second coolant. Each second cooling channel is operable to cool laser gas prior to the laser gas entering into one of the corner housings. The gas laser further includes a temperature control device, in which the temperature control device is selected from the group consisting of a laser gas cooling device, a coolant temperature control assembly, and combinations thereof. The temperature control device is operable to maintain a temperature difference of less than approximately 5 K between the first coolant flowing through the first cooling channel of the corner housing and the laser gas entering into the corner housing.Type: GrantFiled: December 14, 2012Date of Patent: August 26, 2014Assignee: TRUMPF Laser-und Systemtechnik GmbHInventor: Michael von Borstel

Patent number: 6665327Abstract: A spiral-type guide member having a spiral channel extending about an open center portion is provided adjacent the gas inlet end of the laser discharge tube of a gas laser assembly. This guides the entering gas stream about the periphery of the laser discharge tube to improve the distribution of the power of the laser beam over the cross section of the laser discharge tube to the discharge tube of the laser beam 113 is provided for the laser gas in the feed line 123, through which at least part of the laser gas is fed to the laser-discharge tube 103.Type: GrantFiled: April 27, 1999Date of Patent: December 16, 2003Assignee: Trumpf GmbH & Co.Inventors: Michael von Borstel, Detlef Henschler

Patent number: 6624386Abstract: A laser processing machine incorporates a gas flushed beam guiding chamber (3) and an optical element (2) bounding the beam guiding chamber (3) on the beam input side serves the optical element to direct the laser beam (4) into the beam-guiding chamber (3), and a flushing gas intake opening (10) is provided in the beam-guiding chamber (3) near the optical element (2). An optical diaphragm aperture (7, 21) is provided in the beam guiding chamber (3) for shaping the laser beam (4) and it is designed to also serve as a restrictor for the flushing gas. The diaphragm subdivides the beam guiding chamber, and, since only the part of the beam guiding chamber between the optical element and the diaphragm is subject to positive pressure, the amount of flushing gas needed for flushing is reduced.Type: GrantFiled: August 10, 2001Date of Patent: September 23, 2003Assignee: Trumpf Lasertechnik GmbHInventor: Michael Von Borstel

Patent number: 6539045Abstract: A gas laser includes a control to modify the distribution of the intensity of the laser light over the laser beam cross section produced in the lasing gas within at least one laser tube by at least two electrodes and a voltage supply unit by means of which a voltage can be fed to electrodes. A discharge area forms in the lasing gas and this can be affected by adjusting the amplification profile of the laser over the excitation cross section of the laser tube.Type: GrantFiled: December 7, 2000Date of Patent: March 25, 2003Assignee: Trumpf Lasertechnik GmbHInventors: Michael Von Borstel, Frank Ackermann, Mark Geschwandner

Patent number: 6512781Abstract: A gas laser (1) has an optics system and a mode-masking diaphragm in the beam guiding chamber of the laser resonator. The optics system is adjustable between two settings in each of which any higher-order modes of the laser beam (3) are masked out. The Gaussian mode (9) can be generated in one of the two settings, and the ring mode (10) in the other setting. An appropriate control permits switching between Gaussian and ring modes depending upon the intended processing operation.Type: GrantFiled: August 31, 2001Date of Patent: January 28, 2003Assignee: Trumpf Lasertechnik GmbHInventors: Michael Von Borstel, Mark Geschwandner, Tanja Behrends

Patent number: 6466600Abstract: An HF-excited gas laser has a laser tube of ceramic material containing a laser gas, and the tube includes a chemical component which will preclude passage therethrough of secondary radiation of a wavelength within a proscribed range which would interact with the material of the laser tube to create defects therein. The chemical component to prevent damage to the laser tube may be provided as a layer on its inside surface which is essentially impermeable to and/or reflects the secondary radiation back into the lasing gas. Alternatively, the material of the laser tube may incorporate the chemical component, preferably over the portion of the wall adjacent its inner surface.Type: GrantFiled: April 2, 1999Date of Patent: October 15, 2002Assignee: Trumpf Lasertechnik GmbHInventor: Michael Von Borstel

Patent number: 5590146Abstract: In a gas laser (1) with a laser gas circulation path (5) in which a fan (4) conveys the laser gas (6) through a laser discharge space or tube (2) and a cooling system (3a, 3b), the gas throughput is increased by a bypass (8) of the laser discharge space (2). In the bypass may be a filter, cooler and catalyst for treating that portion of the laser gas flowing therethrough. The volume of gas diverted through the bypass may be adjusted to improve the efficiency of the laser.Type: GrantFiled: May 19, 1995Date of Patent: December 31, 1996Assignee: Trumpf Lasertechnik GmbHInventor: Michael von Borstel

Patent number: 5351263Abstract: Known power lasers have outstanding electrical, optical and mechanical properties, in spite of different temperature conditions during switching on and during operation. However, they are expensive. These properties are retained, despite cheaper production costs in that, starting from a solid monolithic optical bench, several mirror blocks and intermediate blocks are mechanically rigidly connected to this, and are shaped such that they do not deflect during chip-removing machining, and those bores necessary for the laser path are only then provided.Type: GrantFiled: July 1, 1993Date of Patent: September 27, 1994Inventors: Michael von Borstel, Michael Hacker, Heinz J. Prokop, Reinhard Wollermann-Windgasse
