On November 6, 2025, the FusioTile project meeting took place in Ilmenau with experts from Marvel Fusion, ZEISS Microoptics, Fraunhofer IOF, LensTec Jena GmbH, and the Nanofabrication and Nanomeasurement Technology Research Group at the TU Ilmenau at invitation of Jun.-Prof. Thomas Kissinger. 

The project promotes the development of large-format pulse compression gratings (PCGs) for next-generation high-power laser systems and is supported with 11 million euros from the German Federal Ministry of Research, Technology and Space (BMFTR).

The goal of FusioTile is to establish new manufacturing processes in Germany for producing PCGs on a meter scale – a dimension that has so far been scarcely achieved. These gratings are considered a technological bottleneck for applications such as laser fusion, high-energy physics, and other fields of photonics. The Institute for Process Measurement and Sensor Technology (IPMS) at the Technical University of Ilmenau uses its expertise in metrology for the compact, interferometer-based precision positioning of the lithography systems used.

Once developed, these gratings can be integrated into laser systems operating at 100 joules energy levels. The outcomes of FusioTile will not only lay the foundation for advanced laser fusion systems but also open the door to new optical technologies across a wide range of industrial and scientific fields. The project represents a key technological milestone, poised to strengthen Germany’s global position in high-power laser and photonics research.

During the project meeting, the partners reported that the design phase across all participating institutions is now nearly complete, paving the way for the transition from conceptual work to hands-on implementation. Significant progress has also been made in the manufacturing of demonstrators and experimental setups. These results underscore the consortium’s strong momentum toward realizing the next iteration of prototypes.
