Introduction
Active Fiber Systems GmbH (AFS) offers an array of high-power femtosecond lasers, including entire pump-probe femtosecond beamlines covering the MIR-VIS-UV to XUV spectral range. Our customers can harness these cutting-edge tools to explore a wide range of pump-probe experiments, shedding light on ultrafast dynamics in materials and paving the way for groundbreaking discoveries. Driven by either our own lasers or Amphos/Trumpf systems, we have access to an unparalleled portfolio of ultrafast laser technologies.
AFS implements the usual addons that are needed to work with your beamline that is XUV focusing and monochromator or differential pumping stages. We include the entire beam path for XUV and OPA beams up to the target chamber including optical translation stage for scanning. We include multiple delay lines to match the temporal offset between both arms of the pump-probe experiment. We will be able find flexible solutions to achieve a smooth interface between our system and your target chamber.
AFS – We pump, you probe!
The following specs show only our exemplary main platform using an Ytterbium-60 60W | 200µJ | 250fs driver laser. We happily customize a beamline excactly to your needs. For example, much stronger lasers (up to 2kW, 20mJ, 300fs) can be used as well. Please get in contact with us to customize your beamline.
