Products & Services

The technology fields Lasers and Optical Systems focus on developing innovative laser beam sources and high-quality optical components and systems. Fraunhofer's team of experienced laser engineers builds beam sources which have tailor-made spatial, temporal and spectral characteristics and ranging from μW to GW. Furthermore, this technology field has a great deal of expertise in beam shaping and guiding, packaging of optical high power components and designing optical components.

In general, the lasers and optics developed at Fraunhofer ILT can be applied in areas ranging from laser material processing and measurement engineering to illumination applications and medical technology, all the way to use in aerospace applications, quantum technology and pure research. Whether our customers are laser manufacturers or users, they do not only receive tailor-made prototypes for their individual needs, but also expert consultation to optimize existing systems.

Multiphysics Modeling of High-Power Semiconductor Lasers

The simulation software SEMSIS, which was developed at Fraunhofer ILT, allows multiphysics modeling of edge-emitting lasers and VCSELs considering their electrical, optical, thermal and mechanical properties in a self-consistent manner. Special use-cases include the prediction of the lateral emission characteristics of broad-area emitters and the computation of threshold values for catastrophic optical damage (COD) of edge-emitting lasers under external optical feedback.

High Fidelity Quantum Frequency Conversion as Key Technology for a Quantum Internet

In a few years, quantum computers could perform complex calculations in the shortest possible time, revolutionizing information technology. Just as classical computers have been interconnected by the internet since 1969, researchers want to network distributed quantum computers in the future. With the architecture of our quantum frequency converter, we are currently setting a world record for low-noise and, in perspective, signal-to-noise performance.

Increased Productivity of Laser Powder Bed Fusion Through a Movable Multi-Scanner Processing Head

When increasing the usable build-volume of conventional Laser Powder Bed Fusion (LPBF) systems, the challenge is to realize a homogeneous shielding gas flow over the entire powder bed. An increase in productivity is also necessary to be able to use such systems economically. To meet these challenges, the Fraunhofer ILT has developed a novel LPBF machine concept (build-volume: 1000x800x350 mm³) based on a movable processing head and five fiber lasers as part of its lighthouse project futureAM.
