| 20120128294 | Optical Beam Switch - An optical beam switch includes at least one input optical wave guide, multiple output optical wave guides and an optical switching element for selectively switching a light beam guided in the at least one input optical wave guide to one of the output optical wave guides, in which the switching element is between the at least one input optical waveguide and the multiple output optical waveguides. The optical switching element includes a beam propagation element and an optical focusing system, where the beam propagation element has two mutually opposed end faces and where either the beam propagation element or the optical focusing system can be deflected and/or twisted transversely to an optical axis. The at least one input optical wave guide is attached to a first end face of the beam propagation element, and the output optical wave guides are attached to a second end face. | 05-24-2012 |
| 20120020382 | Determining the Degradation and/or Efficiency of Laser Modules - A method for monitoring a laser system including a plurality of laser modules connected in series, there being connected in parallel to each laser module a bypass arrangement for bridging the corresponding laser module, includes determining a first laser power of the laser system with a plurality of laser modules operational; activating the bypass arrangement of at least one laser module so that at least one of the plurality of laser modules is bypassed; determining a second laser power of the laser system with the at least one of the plurality of laser modules bypassed; and monitoring the laser system based on a difference between the first and second laser power. | 01-26-2012 |
| 20110210106 | Method For Laser Fusion Cutting Without Cutting Gas - A method for laser fusion cutting of a metal workpiece including applying a laser beam to the workpiece, where a kerf is melted in the workpiece by the laser beam and a laser beam diameter in a working point is configured to expel molten material from the kerf without cutting gas. | 09-01-2011 |
| 20110194816 | Optical Fiber Having Cladding Scattering Centers - An optical fiber is designed to transmit high-power laser radiation. The optical fiber includes a fiber core, and an inner fiber cladding surrounding the fiber core, where the inner fiber cladding is configured to carry the laser radiation in the fiber core. The optical fiber also includes a first outer fiber cladding surrounding the inner fiber cladding. The first outer fiber cladding has a capillary-free longitudinal section and has a smaller refractive index than the refractive index of the inner fiber cladding. The optical fiber includes an outermost fiber cladding surrounding the first outer fiber cladding. The outermost fiber cladding has scattering centers that surround the capillary-free longitudinal section, where the scattering centers scatter laser radiation emerging from the inner fiber cladding through the first outer fiber cladding along the capillary-free section. | 08-11-2011 |
