Table-top soft x-ray source for XAS experiments with photon energies up to 350 eV
O. A. Naranjo-Montoya, M. Bridger, R. Bhar +5
We present a table-top setup for femtosecond x-ray absorption spectroscopy based on high harmonic generation (HHG) in noble gases. Using sub-millijoule pump pulses at a central wav…
A modular table-top setup for ultrafast X-ray diffraction
Wei Lu, Matthieu Nicoul, Uladzimir Shymanovich +4
We present a table-top setup for femtosecond time-resolved X-ray diffraction based on a Cu Kα (8.05 keV) laser driven plasma X-ray source. Due to its modular design it provides hig…
A femtosecond time resolved view of vibrationally assisted electron transfer across the metal/aqueous interface
Zhipeng Huang, Manuel Bridger, Oscar A Naranjo-Montoya +4
Understanding heterogeneous charge transfer is crucial if we are to build the best electrolyzers, fuel cells and photoelectrochemical water splitting devices that chemistry allows.…
Time-resolved diffraction with an optimized short pulse laser plasma X-ray source
Mohammadmahdi Afshari, Philipp Krumey, Dennis Menn +4
We present a set-up for time-resolved X-ray diffraction based on a short pulse, laser-driven plasma X-ray source. The employed modular design provides high flexibility to adapt the…
Acoustic response of a laser-excited polycrystalline Au-film studied by ultrafast Debye-Scherrer diffraction at a table-top short-pulse X-ray source
W. Lu, M. Nicoul, U. Shymanovich +5
The transient acoustic response of a free-standing, polycrystalline thin Au film upon femtosecond optical excitation has been studied by time-resolved Debye-Scherrer X-ray diffract…
Towards high power broad-band OPCPA at 3000 nm
Manuel Bridger, Oscar Naranjo-Montoya, Alexander Tarasevitch +1
High-energy femtosecond laser pulses in the mid-infrared (MIR) wavelength range are essential for a wide range of applications from strong-field physics to selectively pump and pro…
Towards attosecond pulse synthesis from solids: spectral shaping, field autocorrelation, and two-color harmonic generation
A. Seyen, R. Kohn, U. Bovensiepen +2
Harmonic generation from solid surfaces is a promising tool for producing high energy attosecond pulses. We report shaping of the harmonic spectrum to achieve the bandwidth necessa…
Ultrafast inhomogeneous magnetization dynamics analyzed by interface-sensitive nonlinear magneto-optics
Jinghao Chen, Jens Wieczorek, Andrea Eschenlohr +3
We analyze laser-induced ultrafast, spatially inhomogeneous magnetization dynamics of epitaxial Co/Cu(001) films in a 0.4-10 nm thickness range with time-resolved magnetization-ind…
Separation of ultrafast spin currents and spin-flip scattering in Co/Cu(001) driven by femtosecond laser excitation via the complex MOKE
J. Wieczorek, A. Eschenlohr, B. Weidtmann +5
Ultrafast magnetization dynamics in metallic heterostructures consists of a combination of local demagnetization in the ferromagnetic constituent and spin-dependent transport contr…
Efficient Non-Resonant Absorption in Thin Cylindrical Targets: Experimental Evidence for Longitudinal Geometry
A. Akhmeteli, N. G. Kokodiy, B. V. Safronov +3
Experiments provide a qualitative confirmation of significant absorption of a wide electromagnetic beam propagating along a thin conducting cylinder (the diameter of the cylinder c…
Efficient Non-Resonant Microwave Absorption in Thin Cylindrical Targets: Experimental Evidence
A. Akhmeteli, N. G. Kokodiy, B. V. Safronov +3
Significant (up to 6%) absorption of microwave power focused on a thin fiber (the diameter is three orders of magnitude less than the wavelength) by an ellipsoidal reflector is dem…
