TOPTICA Photonics AG, Gräfelfing

TOPTICA Photonics AG is a privately held laser manufacturing company located in Gräfelfing, Germany. More than 180 people develop, produce, and provide research grade lasers for scientific applications and industry grade lasers for OEM integration. Key technologies comprise: tunable single-frequency diode lasers from 190 nm to 2880 nm; ps, and fs pulsed fiber lasers from 488 nm to 2100 nm; multi-color laser engines; THz systems for frequency-domain or time-domain spectroscopy; as well as high power laser diodes and semiconductor optical amplifiers (eagleyard Photonics GmbH, Berlin, owned by TOPTICA since 2013).

Emerging from a scientific environment about 19 years ago, TOPTICA has become the home for many graduates. Physicists and engineers – many with a Ph.D. – are to be found in management, production, service, sales, marketing, product management, and in the R&D department which consists of more than 60 people. The scientific expertise of the employees comprises quantum optics, atom optics, and laser physics in general as well as metrology, optical clocks, ion trapping, and nonlinear optics in a strongly project-related sense. The high-tech environment, a scientific atmosphere, and the professionalism of a well-established industrial company are the breeding grounds for challenging novel projects.

TOPTICA has accumulated vast experience in nonlinear frequency conversion of cw lasers down to deep UV wavelengths (> 190 nm) and a strong background in narrow-linewidth tunable diode lasers. The first single frequency diode laser product was released as early as 1995, and the first frequency-doubled and frequency-quadrupled versions entered the market in 1998 and 2001, respectively. Since then, TOPTICA has constantly improved its laser systems, inventing new diode laser designs and control electronics for narrow-linewidth laser solutions. This led to an increase of available wavelengths and output power as well as improved precision in power and frequency control in order to offer unique research-grade equipment to scientists for their tasks. Recent developments include high power cw lasers in the yellow wavelength range (e.g. > 20 W at 589 nm), as well as cw lasers between 190 and 200 nm.
