TRUMPF participates in Hotstack development project

Ditzingen, 23 February 2024 – In the near future, the laser will generate X-rays or particle beams as a so-called secondary beam source. Companies could use these beams to test the quality of their products without drilling into them or damaging them in any other way. Researchers could use them to test the efficacy of drugs without having to wait in large research facilities. To generate these beams, the laser needs even more power. The TRUMPF site in Berlin is therefore researching how particularly powerful laser diodes can be produced economically. 

For example, the developers are focusing on strong pulse energies and high pulse powers. For the first time, miniaturised laser diode stacks with radiation areas of approx. 1 x 2 cm are to achieve pulse powers of more than 20 kW laser power at room temperature. At the same time, production automation solutions will reduce manufacturing costs and increase the safety of the production process.

 HOTSTACK is a "ProFIT Innovation" project and is co-financed from 2023 to 2025 by the European Regional Development Fund (ERDF) Berlin. In addition to TRUMPF, the Ferdinand Braun Institute, the Leibniz Institute for High Frequency Technology (FBH) and the companies Finetech and LayTec are involved in the project.
