Frank has a physics degree from University Hannover, a PhD in cold atom physics from University Bonn, both with Prof. Dieter Meschede, and after a Postdoc with Prof. Ed Hinds in the UK, he started to work in the Central Research Group of Bayer AG.

Already in the important phase from 2002 to 2010, Frank accompanied the steady growth of TOPTICA as VP of R&D. When in 2009 the company TILL Photonics GmbH was acquired by TOPTICA and then sold to FEI München GmbH, Frank was the acting General Manager, before he rejoined the TOPTICA group.

Wilhelm Kaenders states: “For me, it was an honor and pleasure to start in 1998 and grow the company together with Thomas Weber, at the time as a five person endeavor with focus on scientific and optical data storage markets. We were quickly able to identify and attract excellent people to work with us, and most importantly, to adapt and meet market demands over the last three decades. As TOPTICA group, we have doubled our revenue and workforce since 2020”.

Frank Lison: "I'm excited to take over the role of CTO at TOPTICA. The company’s strong foundation in scientific excellence and laser technology is something I value highly. Together with our teams, I look forward to advancing our laser technologies further."
