The Soft X-ray Spectroscopy and Microscopy group led by Jan Rothhardt is based at the Helmholtz Institute Jena and the Institute of Applied Physics. It focuses on the development and applications of high photon flux XUV and soft x-ray sources. Such sources are enabled by high harmonic generation with high average power femtosecond fiber lasers. This combination enables average powers up to the Milliwatt level in the XUV. In addition, these source provide excellent beam quality and spatial coherence, which enables coherent diffraction imaging down to the nanoscale. Moreover their ultrashort pulse duration enables ultrafast spectroscopy of fundamental dynamics in atoms, molecules and (highly-charged) ions.
Dr. Rothhardt investigates matter on smallest spatial and temporal scales by using modern laser-based XUV and soft x-ray sources. His research interests include:
