Hot or Cold Ablation – That's the Question

Markus Nießen received his degree in physics from RWTH Aachen University in 1991. In 1992, he became a research associate at the Fraunhofer Institute for Laser Technology ILT and switched to the Chair for Laser Technology LLT of RWTH Aachen University in 1995, where he received his doctorate in 2005. His dissertation demonstrated the function of numerical handling of free boundary value problems in modelling. His field is the modelling and numerical simulation of dynamical processes in laser-induced material processing, especially the numerical simulation of free boundary value problems.

Lisa Bürgermeister studied physics at RWTH Aachen University. She graduated in September 2010 with a diploma thesis at the Department of Nonlinear Dynamics of Laser Processing (NLD). Afterwards, she started working as research associate at the Fraunhofer Institute for Laser Technology ILT. Her field of interest is the mathematical modelling of physical processes. At the ILT, her focus lies on the ablation of metal and glass with ultrafast laser pulses.

Nelli Hambach studied mechanical engineering at the RWTH Aachen University. She works as a scientist in the Department for Micro- and Nanostructuring at the Fraunhofer Institute for Laser Technology ILT since 2010. Her field of research is 3D structuring with ultrafast lasers and high density perforation of thin materials with both single and multiple beams.
