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.

 Forschungs- und Entwicklungsvorhaben nach der Richtlinie des Freistaats Thüringen zur Förderung von Forschung, Technologie und Innovation (FTI-Richtlinie)

Gewährung eines Zuschusses aus den Mitteln des Europäischen Fonds für die regionale Entwicklung (EFRE-OP 2014-2020) und aus Landesmitteln

The project is sponsored by Freistaat Thüringen no 2015 FE 9157

The technology of coherent combining ultrashort laser pulses will be developed into a state allowing to use it for commercial available laser systems. The focus lies on reliability, compactness and long-term stability. The final goal is to offer  ytterbium-based laser systems with unprecedented power levels but an usability that does not differ from their single-emitter counterparts

We are currently working on it



Aus Mitteln des Bundesministeriums für Bildung und Forschung (BMBF) bewilligt über Projektträger VDI

Zuwendung aus dem Bundeshaushalt, Einzelplan 30, Kapitel 3004, Titel 68325, Haushaltsjahr 2016

The project is sponsored by BMBF no 13N13971 (VDI)

Today, AFS’s fiber laser systems are able to generate highest power levels and address therewith a plethora of applications. However, so far these systems are all ytterbium-based and emit around 1030nm central wavelength. Our goal within Nukleus is to expand the available parameter space to the 2µm-wavlength range by using thulium-doped fibers

Aus Mitteln des Bundesministeriums für Bildung und Forschung (BMBF) bewilligt über den Projektträger Jülich

Zuwendung aus dem Bundeshaushalt, Einzelplan 30, Kapitel 3004, Titel 68510, Haushaltsjahr 2016

This project is sponsored by the BMBF no. 03WKCV02B (PtJ)

The goal of the research activities is to scale the average and peak power being delivered by one fiber amplifier to further improve AFS fiber laser systems
