Active Fiber Systems GmbH is located in Jena known as the ‘City of Photonics’ in Germany. Active Fiber Systems GmbH (AFS) is a technological leader for high-power femtosecond laser systems. Our employees have pushed the boundaries of what is possible over the last decade. Our solutions range from compact options all the way to complex high-power femtosecond laser beamlines with multiple output ports. All of our high-power laser systems are fully-based on fiber amplifier technology – developed in Jena, Germany.

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, excellent performance and turnkey reliability. During the last two decades, ultra-short-pulse fiber-laser systems have been continuously improved in Jena’s research institutes (e.g. Fraunhofer IOF, Institute for Applied Physics). The laboratory results are ground-breaking; several world records in performance are held in Jena. Today, as a spin-off, AFS even surpassed the performance of these research laser systems in many parameters and has become a world-wide technological leader in many fields of high-power laser development.

The self-defined mission of AFS is to transfer laboratory setups with world-record parameters to reliable laser systems suitable for scientific and industrial applications. We have been selling high-power fiber lasers for more than a decade now and continue to push the boundaries of what is possible.

Among the key features of AFS’s pulsed fiber lasers are their compact dimensions, optimized production costs as well as fully customizable outstanding laser parameters.

Since autumn 2020 we are certified according to ISO 9001:2015.
