    Owing to the progressing coronavirus pandemic, the Fraunhofer Institute for Laser Technology ILT has decided to cancel the International Laser Technology Congress AKL in 2020. The safety and health of our attendees, partners and employees has top priority for us. The next AKL will take place from May 4 to 6, 2022, thus maintaining its regular biennial rhythm. However, so that interested parties do not have to wait another two years for the live demonstrations in Europe's largest laser system park, which are firmly anchored in the AKL, Fraunhofer ILT intends to open its doors as early as this autumn and in 2021 for various planned symposia in Aachen – provided that the general conditions allow it again.

    Aachen. The Digital Photonic Production (DPP) Research Campus has been recommended for the 2nd funding phase by the jury. Within the framework of the second funding phase, up to 2 million euros of funding per year are now available. With an enhanced concept and 13 new industrial partners further exciting possibilities for joint basic research under one roof are thus opening up. New official speaker will be Prof. Constantin Häfner, Director of the Fraunhofer Institute ILT since November 2019 and holder of the Chair for Laser Technology LLT at RWTH Aachen University.

    AKL’20, the 13th edition of the “AKL – International Laser Technology Congress”, will take place in Aachen from May 6–8, 2020. It addresses the entire laser community: from laser manufacturers to experienced users and laser novices. A total of 87 speakers will present examples of innovative solutions from industrial practice and the latest research results, covering all target groups. As an added attraction, the 600-plus participants will be invited to experience “Laser Technology Live” in more than 90 presentations at the Fraunhofer Institute for Laser Technology ILT, which holds Europe’s largest laser park. The highlight of this year’s event is the inauguration of the institute’s new Battery Lab, which will showcase the use of lasers in the manufacture of battery cells and modules.

    Experts in composites strive to develop and research special combinations of materials for lightweight construction and other innovative applications – results of their work will be on show at JEC World in Paris from March 3 to 5, 2020. As the world’s leading trade fair for the composites industry, JEC World offers comprehensive insights into the entire value chain of custom material manufacturing and processing. The Aachen-based Fraunhofer Institute for Laser Technology ILT will be taking the opportunity to showcase laser-based processes for lightweight materials and hybrid joints.

  • A carbon fiber preform drilled using a USP laser beam with a star-shaped cut-out and a perfectly proportioned metal insert.

    Carbon fiber reinforced polymer (CFRP) components are usually assembled using fasteners. These are typically glued into the CFRP component once it has been cured and drilled. The consortium behind the CarboLase project came up with a new method, using an ultrashort pulsed laser to drill the holes for the fasteners in the textile preform with micrometer-scale accuracy. Integrating the fasteners in these high-precision cut-outs before the CFRP component is cured saves time by shortening the production process. In 2019, the project team’s efforts were rewarded with the prestigious CAMX Award in the “Combined Strength” category.

    Microplastics enter our wastewater and the environment on a daily basis. Yet wastewater treatment plants struggle to filter out enough of these tiny plastic particles. Fortunately, help is on hand in the form of the SimConDrill research project, which the German Federal Ministry of Education and Research (BMBF) has been funding since 2019. Combining the expertise of five partners from industry and research, the aim of the project is to jointly develop a filter featuring tiny, laser-drilled holes that can remove plastic particles as small as 10 micrometers from wastewater. This remarkable innovation has now been nominated for the prestigious Green Award. Until February 14, 2020, you can vote online at https://greentechfestival.com/en/awards/ to support the project.

    Laser Colloquium Hydrogen LKH2: fast and reliable fuel cell manufacturing

    Press Release / 15.1.2020

    Premiere: Fraunhofer ILT will be holding its Laser Colloquium Hydrogen LKH2 in Aachen on March 18, 2020. It will focus on laser welding and cutting of bipolar plates and the entire fuel cell manufacturing process chain.

    Interest in the use of fuel cells is steadily increasing as a result of the shift toward e-mobility and the broader adoption of renewable energy sources. To examine this development, the Fraunhofer Institute for Laser Technology ILT is organizing the first Laser Colloquium Hydrogen LKH2, which will take place in Aachen on March 18, 2020. The event will focus not only on laser cutting and welding of fuel cell components, but also on the execution and monitoring of the entire process chain.

  • A diode-pumped alexandrite laser reduces the size and energy requirement of the LIDAR system by a factor of 100.
    © Fraunhofer ILT, Aachen, Germany.

    Higher atmospheric layers are becoming more and more interesting for climate researchers, but the areas above 40 km are only directly accessible with sounding rockets. A newly developed LIDAR system (Light Detection and Ranging) with a diode-pumped alexandrite laser will soon make such research possible remotely. Scientists from the Leibniz-Institute of Atmospheric Physics (IAP) and the Fraunhofer Institute for Laser Technology ILT are developing a system that is not only easy to transport but also works independently. In the future, a LIDAR network will be able to deliver data from the atmosphere continuously and on a large scale.
