Work with Beat Neuenschwander | NotedSource
I have more than 20 years of experience in laser based
microprocessing with ultrashort pulses. Our focus lies on
process optimization and process scale up (i.e.
mechatronics) in many different fields. We made valuable
contributions in these fields within different applied
research projects, publications, book chapters and talks
at international conferences. Additionally, I served in
different conference committees, initiated with others the
network swissphotonics and acted as an expert for the
Swiss founding agency innosuisse (former CTI).
