Whether in medical technology, quantum technology or semiconductor production, optical systems are an integral part of many high-tech applications. To ensure that lenses, mirrors and other components meet the highest requirements, manufacturing needs processes that combine precision, efficiency and flexibility. The Fraunhofer Institute for Laser Technology ILT develops tailor-made solutions for precisely this purpose, solutions that consist of a few highly efficient and extremely productive individual steps. Laser-based optics manufacturing enables the industry to produce dimensionally accurate and functional components with low roughness, from prototypes to series production, from microlens arrays to macro-optics, from spheres to free-form optics.

Ultrashort pulse lasers have been a hot topic in precision material processing for years. To discuss the later developments, the UKP workshop in Aachen has become the meeting place for the constantly growing community. This year, the major topics were beam sources, system technology, beam shaping and, of course, applications. Many of the innovations presented had a common goal: scaling down to smaller structure sizes and scaling up productivity.

Thanks to synchrotron radiation, welding processes can be observed in greater detail than ever before – live and in real time! Researchers from Fraunhofer ILT and RWTH Aachen University – Chair for Laser Technology University are working at DESY to make vapor capillaries, melt movements and defects visible. Their findings optimize battery and microelectronics production and pave the way for the development of new materials.

The aerospace industry is undergoing profound change. Companies are facing the challenge of having to drastically shorten development cycles, develop more sustainable technologies and reduce costs, all at the same time. In addition, advances in satellite technology require new manufacturing approaches to make systems smaller, lighter and more powerful. While government space programs continue to play a major role here, private players such as SpaceX, Blue Origin and Rocket Lab are driving the commercialization of space travel and setting new standards for efficiency and profitability: Competition has never been so fierce.
