  • Lasers are the key to mastering challenges in lightweight construction

    Many joining and cutting processes are possible only with lasers. New technologies make it possible to manufacture metal components with hollow structures that are significantly lighter and yet just as stable as solid components. In addition, lasers can be used to combine various lightweight construction materials and steels with each other. The Fraunhofer Institute for Laser Technology ILT in Aachen is presenting a range of such solutions at the LASER World of Photonics trade fair from June 22 to 25, 2015 in Munich, Germany, (Hall A3, Stand 121).

  • Searching for the perfect laser beam

    Today’s lasers for cutting applications are the best-selling industrial laser beam sources worldwide. Current analyses estimate that these lasers have roughly 50 percent of the market, with the most dominant application being the precise, flexible and highly productive 2D cutting used to produce nearly any contour in sheet metal blanks. At the same time, completely new cutting methods – for instance, perforations or the precise shaping of glass displays for mobile devices – are on the verge of entering industrial production. Current research is focused on increasing expertise in forming fiber-guided laser beams for sheet metal cutting and transferring that knowledge to damage-free glass cutting in the display industry as well as water-jet-guided precision cutting of small parts. As part of the EU’s HALO project (“High power Adaptable Laser beams for materials processing”), scientists at the Fraunhofer Institute for Laser Technology ILT are working on distributing the laser beam’s intensity in a way that meets the highest quality requirements while conserving resources. The project results will be presented at the LASER World of Photonics 2015 in Munich.

  • UKP-Workshop: Ultrafast Laser Technology 2015 - Productivity is the key

    USP ablation on a roll-to-roll machine with beam splitting for the parallel processing of organic solar cells.

    New ways to increase productivity were top of the agenda at this year’s UKP-Workshop: Ultrafast Laser Technology, with many aspects of the subject presented and debated in depth – from beam sources and process engineering to applications. The conclusion: ultrafast laser pulses have arrived in material processing, new applications are becoming possible thanks to constant developments not least in process engineering, and the market for ultrafast laser systems is enjoying exceptional growth.

  • Electrical Storage: Safe Contacts between Battery Cells by Laser Beam Welding

    Oscillation laser welding creates safe electrical contacts between battery cells.

    The Fraunhofer Institute for Laser Technology ILT has developed a new laser welding technology for temperature-sensitive cylindrical battery cells that is now ready for series production. Since 2009 the experts from in Aachen, Germany have been working on battery joining – the process of connecting individual cells into packs. They are currently working with other Fraunhofer Institutes to put together a complete battery pack.

  • Femto Photonic Production: New techniques using ultrafast lasers for the manufacturing of tomorrow

  • Short Laser Pulses for Material Deposition with Cold Spray Technology

    High-speed deposition of copper on aluminum segments

    In a new EU-funded project, ultra-short laser pulses modify material surfaces so that metal powder from a cold gas jet can adhere more easily. With Cold Spray Technology, coating lightweight materials such as plastics or carbon fiber reinforced plastic (CFRP) becomes significantly simpler. The EU research project “Efficient Manufacturing of Laser-Assisted Cold-Sprayed Components” (EMLACS) unites five partners from industry and research who want to extend low-pressure cold gas spraying to new applications.
