    Experts from 13 different Fraunhofer institutes are working on the development of multi-kW ultrafast lasers and various applications in the Fraunhofer Cluster of Excellence Advanced Photon Sources CAPS. A user facility with application laboratories in Aachen and Jena is being created for this purpose, laboratories in which partners from industry and research can work with the new technology.

    Car makers currently use a variety of methods to emboss plastic panels for vehicle interiors. However, manufacturing the tools required for this purpose is an extremely time-consuming process. This situation can be improved using a new laser machine that triples the rate at which these tools are produced while facilitating even more complex structures. The expertise required for the various components and processes was developed as part of the “eVerest“ project in collaboration with partners from research and industry.

  • USP Lasers Conquer Macroprocessing

    Press Release / 25.4.2019

    Dr. Arnold Gillner: The challenge is to get the photons to the workpiece.

    Ultrashort pulse (USP) lasers have become firmly established in science and micromachining. At this year's “UKP-Workshop: Ultrafast Laser Technology” in Aachen, a new trend has emerged: Macroprocessing. Since multi-100-watt USP lasers up into the kW range have become available, the industry is looking at them with great interest for large-area applications. For this purpose, the institute is developing the complete process chain right through to fully digitized processes.

  • Laser beams are optimized by beam shaping for in-volume structuring of glass to manufacture 3D parts.

    Separate glass with any desired contour? Without generating dust and reworking the edges? This is possible, even quickly, with specially shaped ultrashort laser pulses. The Fraunhofer Institute for Laser Technology ILT is developing a technology that – with refractive and diffractive optical elements – gives laser beams a form optimally adapted to the respective task. In addition, the applications go far beyond separating glass: In the future, head-up displays for the automotive industry will also be produced.
