Diamond Lenses Make Laser Optics Significantly Lighter

Diamonds are not only a girl's best friend, but synthetic diamonds are also attractive as a material for laser optics: thanks to their extremely high refractive index and excellent heat conduction, laser optics made with them are ten times lighter than conventional laser optics. Fiber lasers in the kW range could, thus, operate with greater flexibility. Three Fraunhofer institutes have optimized the production and processing of diamonds in recent years, and the first cutting system with diamond lenses is being tested.

Aachen Center for 3D Printing: Official launch of the world’s largest SLM facility

For their joint project, the Aachen Center for 3D printing, the Aachen University of Applied Sciences and the Fraunhofer Institute for Laser Technology ILT have ambitious plans. On June 1, 2017, they officially opened the world’s largest SLM facility, located in the new Digital Photonic Production industry building on the RWTH Aachen campus. Concept Laser’s new XLine 2000R selective laser melting system plays a pivotal role in the SLM-XL research project, which is intended to accelerate and optimize the entire manufacturing process for large, metal components. Scientists are working closely with the Digital Photonic Production research campus, which is located in the same building and funded by the German Federal Ministry of Education and Research (BMBF).

Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. To retain this technological edge, many companies already have to process metal components to the exact micrometer with zero waste. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing in the micrometer range to provide an energy- and resource-efficient way of testing the shape and orientation tolerances of products during the manufacturing process. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
