Subject	Engineering; Physics
Keyword	Laser Percussion Drilling, High-Speed Synchrotron X-ray Imaging, Spatial Beam Shaping, Laser-Material Interaction
Related Publication	Is Supplement To: Robin Klöpfer, Tobias Spieth, Felix Teufel, Michael Haas, Tobias Florian, Christoph Spurk, Alexander Olowinsky, Guilherme Abreu Faria, Andreas Otto, Christian Hagenlocher ,Thomas Graf (2026). High-speed X-ray imaging of borehole geometry formation during deep ultrafast laser percussion drilling using spatially shaped beams.
Notes	This work was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) - 510793395. The presented investigations were carried out within the cooperation “Laser Meets Synchrotron” (www.laser-meets-synchrotron.de). The experimental setup and its operation were funded by the Deutsche Forschungsgemeinschaft e.V. (DFG, German Research Foundation) within the framework of the Collaborative Research Centre SFB1120-236616214 “Bauteilpräzision durch Beherrschung von Schmelze und Erstarrung in Produktionsprozessen”. We acknowledge Hereon (Geesthacht, Germany) and DESY (Hamburg, Germany), members of the Helmholtz Association HGF, for the provision of experimental facilities. The experiments were carried out at Beamline P61 of DESY PETRA III as part of proposal BAG-20230679, and we would like to thank G. Abreu Faria and all people involved for their support. Furthermore, the authors thank Ekspla and Topac for the loan of the Femtolux 30 laser system as well as Midel Photonics for the provided DOE.
