PERFORMANCE MEETS RELIABILITY

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.

Dual-wavelength picosecond fiber laser for nonlinear microscopy

Compact, alignment-free and all-fiber picosecond laser source for CARS microscopy delivering synchronized pump and Stokes pulses from a single fiber end. This air-cooled and turn-key CARS laser source has a great benefit for the user as the fiber delivery eliminates alignment of the spatial and temporal pulse overlap. High quality and high-speed microscopic multimodal nonlinear imaging is possible by e.g. simultaneously probing the CARS CH-vibrational-levels of lipids around 2850 cm-1, the second harmonic generation (SHG) and the two-photon excited fluorescence (TPEF) signals.

 

APPLICATIONS

  • CARS spectroscopy and microscopy
  • Microscopic multi-modal nonlinear imaging (CARS, SHG, TPEF)

High repetition rate energetic few-cycle pulses

Based on our high performance ultrafast fiber laser systems nonlinear pulse compression is employed to enter the few-cycle regime. Nonlinear spectral broadening in noble-gas filled hollow-core fibers is the most efficient and power scalable technique to temporally compress high performance femtosecond lasers. In addition, the technique preserves the excellent beam quality of fiber based sources and is scalable to mJ pulse energies and average powers beyond 100 W.
