Active Fiber Systems GmbH (AFS) 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, AFS represents the expertise of innovative solid-state laser development. It is our mission to transfer groundbreaking 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. For example, our record-average-power high-energy few-cycle lasers are ideal sources for the generation of high-harmonic radiation and attosecond pulses.
