Compact laser scanner with 90 percent less construction volume

Galvanometer scanners have been in use in laser material processing for decades. However, a team from the Fraunhofer ILT has now developed a new, particularly compact scanner module for applications in 3D printing, micromachining or medical technology.  


Replacing hand gestures with holography

How do you decide whether a pedestrian needs to wait or it’s safe for them to cross the road in front of a car? In today’s world, car drivers and pedestrians simply exchange a brief eye contact or small hand gestures to express their intentions to one another. But how will future autonomous cars communicate? Researchers involved in the MaMeK project are seeking to answer that question.


Optimizing production processes through modularization

Researchers at the Fraunhofer IWS have developed SURFinpro, a solution that uses artificial intelligence and optical measurement technology to detect, classify and visualize defects in real time, and report them to the plant carrying out the production.


Customized optical measurement technology for production monitoring

At the Fraunhofer IST, systems for improved process control and the automated process management of coating processes are developed on the basis of a holistic understanding of the process. One example is the MOCCA software, which will be demonstrated live at LASER 2023.


Photonic Technologies for the Quantum Internet

Researchers at the Fraunhofer ILT are developing technology for quantum networks of the future. Initial results will be presented at the "World of QUANTUM" trade fair in Munich at the end of June.


Premiere of the Arctic Kind

An electric snowmobile at LASER World of PHOTONICS 2023 in the summer! Why? Trade show visitors have the Finnish startup Aurora Powertrains Oy from Rovaniemi to thank for this premiere of the Arctic kind. Aurora has developed cold-resistant batteries with extremely high energy density for the Arctic temperatures of this region, and the customized joining technology required for this comes from the laser welding experts at the Fraunhofer ILT.


Simultaneous coating and mechanical processing with SMaC

The Fraunhofer ILT has developed a new hybrid process called Simultaneous Machining and Coating (SMaC), which combines laser material deposition with turning, grinding or milling. SMaC allows high-strength coating materials to be applied quickly and efficiently and machined simultaneously.  


New lasers for climate research

Weather reports, climate models or rocket launches – they all need precise data from the atmosphere. To acquire such data, scientists can use LIDAR systems to shoot laser beams into the sky. A team from the Fraunhofer ILT and the Leibniz Institute for Atmospheric Physics IAP has developed a portable LIDAR system that works autonomously.  


MEMS LIDAR systems

With their enormous power density, laser beams can weld and cut steel plates, polish workpieces or build up entire engine blocks layer by layer from metal powder in 3D printing. Highly reflective layers make it possible to use micro-mirror scanners in MEMS technology for precise path control.


Qualified micro scanners for customized medical applications

The potential of micro scanners in medical technology is immense. Fraunhofer IPMS is continuously expanding the application range of scanner mirror technology with novel and patented design solutions and technology modules as well as the integration of artificial intelligence.


Semiconductor disk laser for high-precision quantum frequency converters

As a pump source for high-precision quantum frequency converters, Fraunhofer IAF is developing single-mode semiconductor disk lasers in the wavelength range from 2 to 2.2 µm in the BMBF-funded project HIFI.


Light Modulation in Perfection

Fraunhofer IPMS uses optical microsystems to enable fast and high-resolution light control. By using small, movable mirrors, the institute's photonic systems can modulate light to create unique images and structures. The institute's researchers are implementing 1-axis- and 2-axis tilting mirrors as well as piston mirrors. The mirrors are monolithically integrated on so-called CMOS backplanes.


Focus on Added Industrial Value through Light

The combined Laser Symposium and International Symposium on Additive Manufacturing (ISAM) conference in Dresden from November 29 to December 1, 2023, will show how lasers contribute significantly to added industrial value today and in the future. Artificial intelligence is helping to further push the boundaries of laser-based processes.


New fabrication technique for periodically-poled lithium niobate

Periodically-poled lithium niobate (PPLN) is a nonlinear-optical crystal with specific photonic properties. It is suitable for example for the frequency conversion of laser light. Researchers at Fraunhofer IPM in collaboration with the University of Freiburg have developed a new technique that allows them to structure PPLN with full flexibility and without masks.


Thin metasurfaces instead of thick lenses

Bye bye, lens. Hello metasurface! So-called metasurfaces can help to make optical systems thinner in the future, while at the same time increasing their functionality. The problem: Until now, conventional manufacturing processes have often only been able to realize small metasurfaces, often smaller than one square millimeter. Researchers at Fraunhofer IOF have now succeeded for the first time in producing a metasurface with a diameter of almost 30 centimeters using electron beam lithography - a world record.
