Daniel Metzner, a research assistant at the Laser Institute of Mittweida University of Applied Sciences, completed his collaborative PhD programme leading to a Dr.-Ing. degree on 19 December 2023 at Chemnitz University of Technology, graduating with the overall distinction of magna cum laude. He successfully defended his doctoral thesis, entitled ‘Laser microstructuring of high-alloy steel – Fundamental investigations into the use of high-frequency pulse trains of ultrashort laser pulses”, was defended very successfully – including the oral examination – before the examination board, fellow researchers and in the presence of his family at the Institute of Materials Science at Chemnitz University of Technology.
Over the past four years, Dr.-Ing. Daniel Metzner has conducted intensive basic and applied research into the interaction of solid-state surfaces with high-frequency sequences of ultrashort laser pulses within Professor Steffen Weißmantel’s research group. He has presented these largely novel findings in a high-quality doctoral thesis, and this work has resulted in a series of publications in renowned scientific journals that have attracted significant international attention, as well as three patents.
Application-oriented research is currently being carried out in collaboration with industry partners to utilise the findings obtained during the PhD research. This relates in particular to the production of high-quality microstructures on metal surfaces for various applications. Furthermore, the patented processes for smoothing solid surfaces and removing stubborn dirt deposits form the basis for new and innovative applications. For example, in the coin-making industry, microstructures can be polished with a high degree of selectivity directly during the production process, thereby eliminating the need for subsequent polishing, which previously took several days using conventional methods. Another example is residue on laser-generated microstructures of implants, which is inevitably produced by the manufacturing process itself. Thanks to the patented process, this residue can be removed without leaving any traces, thus posing no risk to the surrounding bone tissue.
