13th “AKL – International Laser Technology Congress”:
May 4–6, 2022 in Aachen – Laser Technology Live already this year!

Owing to the progressing coronavirus pandemic, the Fraunhofer Institute for Laser Technology ILT has decided to organize the next “AKL – International Laser Technology Congress” in two years: The AKL’22 will take place in Aachen from May 4 to 6, 2022. Provided that the general conditions allow, Fraunhofer ILT intends to open its doors to various planned conferences in Aachen as early as autumn 2020 to ensure that interested parties do not have to wait two years for the live demonstrations, firmly anchored in the AKL, in Europe's largest laser system park.

Laser welding processes for martensitic chromium steels ensure a future safe from collisions

Martensitic chromium steels are one of the steel grades with a future, steels that are ideal for automotive applications since they are both lightweight and corrosion resistant. These materials are particularly in demand for the design of collision-safe battery boxes for electric cars. For this reason, the Fraunhofer Institute for Laser Technology ILT in Aachen uses these sophisticated components as demonstration components for laser welding and heat treatment.

Stifterverband Prize for Multi-beam Laser Processing

The ultra-short pulse laser is seeing ever wider acceptance among industrial users as a tool for precision manufacturing. In particular, these advances are due to new developments or technological progress in system technology, which increase productivity considerably. Increasing productivity significantly was also the goal of a team from industry and research, which was awarded the Science Prize of the Stifterverband for Collaborative Research at the annual conference of the Fraunhofer-Gesellschaft on October 9. The team has developed a technology in which a laser beam is split into up to 16 partial beams. That means there are 16 tools controlled in parallel and individually to produce functional surfaces.

More flexible battery design with ultrafast laser ablation

The ultrashort pulse (USP) laser has been known to shine whenever highly sensitive material needs to be machined quickly yet gently. The Fraunhofer Institute for Laser Technology ILT has investigated one such application that certainly looks to have a bright future: The Aachen-based researchers developed a quick, reliable and nondestructive method of ablating lithium-ion batteries’ anode material with an ultrashort pulsed laser beam. This ablation technique exposes electrical contact points called tabs.

Producing Nanostructures Cost-Effectively

How can structures smaller than one micrometer be generated? And how can even smaller structures of less than 100 nanometers be produced without great effort? Scientists at the Fraunhofer Institute for Laser Technology ILT have developed several technologies to answer such questions. With these technologies, they can simulate, produce and measure periodic microstructures. They use phase-shifting transmission masks that can efficiently generate nanostructures down to 28 nanometers.
