    Being infected by Cold Atom Physics as a PhD student at the Institute of Quantum Optics in Hannover, and being part of the technology of Prof. Hänsch's group at the Max-Planck-Institute in Garching, Dr. Wilhelm Kaenders started a successful business activity with tunable diode laser technology. "Frequency Division" in the early days and "Frequency Combing" today, have started the Passion of Precision and are still the driving force in TOPTICA's extended scientific product range on its way to mature markets. As cofounder of TOPTICA, he serves together with Dr. Thomas Weber as "Vorstand".

    Dr. Thomas Weber

    President

    Dr. Thomas Weber started his career under Prof. Herbert Walther using LIDAR technology for environmental measurements before he proceeded with his PhD in high-resolution molecular spectroscopy at TU Munich. After being hired as developing physicist at TECHNOLAS GmbH in 1991 his management skills became quickly obvious resulting in finally becoming CEO of the TECHNOLAS spin-off TuiLaser AG. In 1998 he started TOPTICA Photonics AG as one of the cofounders in a combined management and technical role. Dr. Thomas Weber has built up the optical data storage and subsequently the industrial laser activities at TOPTICA and guides the company together with Dr. Wilhelm Kaenders as "Vorstand".
