Automotive technology and mobility

For three decades now, the AKL – International Laser Technology Congress has been established as a key platform for exchange within the laser community. From April 22–24, 544 experts from 21 countries, around 90 speakers, and 57 exhibiting companies and institutions flocked to AKL’26 in Aachen. There, during the Gerd Herziger Session, a panel of high-caliber experts reviewed the developments of the past 30 years and looked ahead to the future of increasingly ubiquitous laser technology.

Laser technology is breaking into new dimensions: Ultrashort-pulse and continuous-wave lasers with average powers in the multi-kilowatt (kW) range promise to boost efficiency for material processing and pave the way for entirely new fields of applications. At the AKL’26 - International Laser Technology Congress, taking place from April 22 to 24, 2026, in Aachen, several sessions will focus on multi-kW lasers.

Solid-state batteries promise greater safety, higher energy density, and new degrees of freedom in cell design. Yet the path from laboratory cell to industrial production is challenging. Laser processes can overcome key hurdles and enable a breakthrough.

State Secretary Matthias Hauer presents funding approval for the InnoWaerm project at Fraunhofer ILT. The project, funded by the Federal Ministry of Research, Technology and Space (BMFTR) with approximately 1.5 million euros, develops high-temperature-resistant lightweight reactors made from titanium aluminide that can be manufactured using additive manufacturing. They are intended to generate hydrogen directly on board aircraft, agricultural machinery, or heavy-duty vehicles.

Industrial manufacturing is under increasing pressure. Sales markets that were considered secure for decades are becoming unstable. Robust supply chains are being threatened. Energy and material costs are rising, markets demand a growing number of variants, and new products must reach production readiness ever faster. In this environment, the laser has established itself as a reliable manufacturing tool. Its physical principles are well understood, and many laser-based processes are mature and proven in industrial use. As a result, the focus of research is clearly shifting. The key question is no longer whether a process can be realized with a laser, but how efficiently, robustly, and economically it can be operated in everyday production.

How can artificial intelligence (AI) contribute to value creation in laser manufacturing technology and optical design? What approaches are there and what is missing to leverage the potential? A conference organized by SPECTARIS and supported by Fraunhofer ILT and the German Association for IT-SMEs in Berlin on October 1 and 2 provided answers.

In its special show "Photonics meets Robotics: AI Success Stories" Laser World of Photonics 2025 will be focusing on the future field of cyberphotonics, and the Fraunhofer Institute for Laser Technology ILT in Aachen is playing a key role in this. Researchers from the institute will give presentations on specific applications and exhibit research results to show how AI and other digital methods are already increasing quality and efficiency in photonics, robotics and laser-based, highly automated manufacturing processes. The special show in Hall A3.433 builds a bridge between LASER and the parallel automatica.
