Electronic quantum coherence in glycine molecules probed with ultrashort x-ray pulses in real time Open
Here, we use x-rays to create and probe quantum coherence in the photoionized amino acid glycine. The outgoing photoelectron leaves behind the cation in a coherent superposition of quantum mechanical eigenstates. Delayed x-ray pulses track…

Full characterization of a phase-locked DUV double pulse generated in an all-reflective shaping setup working under grazing incidence in a broad spectral range Open
Controlling the temporal and spectral properties of ultrashort laser pulses in the visible and near-infrared spectral range by means of a femtosecond pulse-shaping device is a powerful tool with many applications in ultrafast spectroscopy.…

Table-top interferometry on extreme time and wavelength scales Open
Short-pulse metrology and dynamic studies in the extreme ultraviolet (XUV) spectral range greatly benefit from interferometric measurements. In this contribution a Michelson-type all-reflective split-and-delay autocorrelator operating in a…

Electronic Quantum Coherence in Glycine Probed with Femtosecond X-rays Open
Structural changes in nature and technology are driven by charge carrier motion. A process such as solar-energy conversion can be more efficient, if energy transfer and charge motion proceeds along well-defined quantum mechanical pathways …

Auger electron wave packet interferometry on extreme timescales with coherent soft x-rays Open
Wave packet interferometry provides benchmark information on light-induced electronic quantum states by monitoring their relative amplitudes and phases during coherent excitation, propagation, and decay. The relative phase control of soft …

Shaping femtosecond laser pulses at short wavelength with grazing-incidence optics Open
We present the design of an extreme ultraviolet (XUV) pulse shaper relying on reflective optics. The instrument will allow tailoring of the time-frequency spectrum of femtosecond pulses generated by seeded free-electron lasers (FEL) and hi…

Split-And-Delay Unit for FEL Interferometry in the XUV Spectral Range Open
In this work we present a reflective split-and-delay unit (SDU) developed for interferometric time-resolved experiments utilizing an (extreme ultraviolet) XUV pump–XUV probe scheme with focused free-electron laser beams. The developed SDU …
