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.

Nonlinear compression is an elegant way to shorten the pulse duration of pulses beyond the capabilities of the employed laser gain medium.

This option can be applied to a large span of laser system with pulse energies ranging from µJ to several mJ and average powers at the kW-level.

Applying an femtosecond-pulse burst instead of an energetic single pulse holds the promise to significantly improve materials processing at highest average powers. AFS ultrafast fiber-laser systems can be operated in a burst mode with negligible variation of pulse duration over the burst and with a flexible pulse structure.

As a part of AFS leading-edge fiber laser technology, the fast pulse-switching feature provides an optional extension of the laser‘s capability. 

Single-pulse selection can be achieved up to 10 GHz repetition rate with this patented technology. Full control over the pulse sequence is guaranteed on both their occurrence and their amplitude, which can be adapted to the customers needs. Most important, the ultrafast modulator works at highest average power levels without any detrimental effects on the laser characteristics.
