Biography
- Beat Neuenschwander studied physics at the University of Bern and realized 1996 his PhD at the Institute of Applied Physics in the field of diode pumped solid state lasers. From 1997 to 2002 he joined the company Numerical Modelling and since 2000 he is also at the Bern University of Applied Sciences BUAS where he lectures physics and applied laser technology. There he built up the laboratory for laser micro machining and laser surface engineering and became full professor in 2005. His main research topic, where he published more than 55 papers, is laser micromachining with ultra-short pulses and its industrial application. He is founder member of the national thematic network NTN swissphotonics, which he headed from 2008 – 2011 as managing director. Actually, he is expert for the founding agency innosuisse, head of the optics section of the Swiss Society for Optics and Microscopy SSOM and chair of the LASE symposium at Photonics West.
