Post-Doctoral Scientist for Experiments with femtosecond IR/VIS/UV-pulses (f/m/d)

The position

Working closely with the instrument scientists at FXE, the successful candidate will investigate ultrafast processes in matter using femtosecond pulses in the IR/VIS/UV region with the goal to develop and apply advanced instrumentation tools that facilitate the setup of future pump-probe experiments. The specific tasks are:
  • Develop a set of diagnostics tools and -methods that facilitate establishing experimental conditions for femtosecond IR/VIS/UV-optical pump, X-ray probe experiments.
  • Refine the operation principle of these diagnostics tools based on the candidate’s clear scientific understanding of the process following femtosecond X-ray excitation.
  • Develop, maintain and operate a setup to perform all-optical femtosecond pump-probe Transient Absorption and Reflection Spectroscopy using the IR/VIS/UV-pulses as excitation to study light-induced effects in matter, following the candidate’s research profile and interests.
  • Support the FXE instrument operation actively, in particular in all aspects of the use, maintenance and development of the advanced excitation sources and diagnostics.


  • PhD degree in physics or in a related discipline
  • Proven hands-on experience working with femtosecond lasers and with the design, assembly and alignment of optical setups
  • Proven experience with scientific data reduction using Python, Matlab or similar tools
  • Experience with femtosecond pump-probe spectroscopy in the IR/VIS/UV regions and/or experience with THz radiation is an asset
  • Work experience at a large-scale user facility is considered an asset
  • Highly motivated for independent research involving instrumentation and methodology development
  • Excellent communication skills and the ability to work in a multi-lingual, multi-disciplinary team, with English as the working language. Knowledge of German is considered an asset
