The Active Fiber Systems GmbH is located in Jena, known as ‘city of photonics’ in Germany. As a spin-off company from both the Fraunhofer IOF Jena and the Institute of Applied Physics at the University of Jena, the Active Fiber Systems GmbH represents the expertise of innovative solid-state laser development.

Fiber lasers enjoy an excellent reputation as power-scalable diode-pumped solid-state laser concept. Their immunity against thermo-optical issues is combined with efficiency and high performance in fiber based amplification. During the last decade, ultra-short pulse fiber laser systems have been developed in Jena’s institutes. The laboratory results are ground-breaking; several world records in performance are held by those institutes.

The mission of Active Fiber Systems GmbH (AFS) is to transfer experimental results to reliable laser systems suitable for scientific and industrial applications. Among the remarkable features of AFS's pulsed fiber lasers are their compact dimensions, considerably reduced production costs as well as flexible and outstanding laser parameters, which can be customized.
