20 kW laser system for producing high purity crystals

High-purity semiconductor crystals are required for power electronics in electric cars or in photovoltaics. When such crystals reach a diameter of 2 inches, they become relevant for industrial applications. Researchers from Japan and Germany have now developed a method to produce such crystals using a laser-based process, and without a crucible. The team at the Fraunhofer Institute for Laser Technology ILT in Aachen has developed a process-adapted optical system for use with a 20 kW laser.

Fraunhofer ILT coordinates NRW quantum roadmap

At a kick-off meeting in Cologne on January 30, 2024, a group of innovative minds gave the starting signal for a roadmap that will bundle the ongoing activities in the field of quantum technologies at universities, research institutes, start-ups and companies in the federal state of North Rhine-Westphalia (NRW). The two leading state ministries – for culture and science (MKW) and for economy, industry, climate protection and energy (MWIKE) –have commissioned the coordination office QT.NMWP.NRW and Forschungszentrum Jülich with implementing the roadmap. The Fraunhofer Institute for Laser Technology ILT in Aachen is responsible for coordinating it.

Fraunhofer ILT invites industry to join new network for hydrogen technology

The Fraunhofer Institute for Laser Technology ILT is mobilizing the new “Lasers in Hydrogen Technology” network to help suppliers and users exchange their particular expertise about lasers and photonics for hydrogen technology. In this network, participants can discuss current research and development on laser processes for fuel cells and electrolyzers. Research alliances are also to be formed to accelerate the industrial implementation of hydrogen technology. The Aachen institute has set up a hydrogen laboratory as a platform for developing such laser processes, a location that the project partners can use to rapidly advance the technology and that covers the entire process chain from forming technology to testing the cells.

AI has the potential to close control loops

Whether in laser material processing, additive manufacturing and repair processes, laser weed control or the automated design of optical systems: Artificial intelligence has enormous, sometimes disruptive potential in photonics. With around 50 international experts in attendance, the 3rd "AI for Laser Technology Conference" took place at the end of November at the Fraunhofer Institute for Laser Technology ILT in Aachen, and clearly showed that the AI-driven transformation is in full swing.
