Generation of high-fluence and high-intensity hard x-ray attosecond pulses at European XFEL
Ichiro Inoue, Ulrike Boesenberg, Rustam Rysov +41
By combining hard x-ray attosecond pulses from the European XFEL with total-reflection focusing x-ray optics, we generated nanofocused hard x-ray attosecond pulses with intensities…
X-ray Coherent Attosecond Pulse Pair Spectroscopy
Zain Abhari, Thomas M. Linker, Thomas Kroll +14
X-ray free electron laser (XFEL) experiments using self-amplified spontaneous emission (SASE) pulses typically achieve temporal resolutions of order several femtoseconds, as the pu…
Experimental demonstration of attosecond hard X-ray pulses
Ichiro Inoue, River Robles, Aliaksei Halavanau +24
We present the first direct experimental confirmation of attosecond pulse generation in the hard X-ray regime with a free-electron laser. Our experiment is based on measurements of…
Observation of Multiplet Lines in Seeded Stimulated Mn Kα1 X-ray Emission
Thomas Kroll, Margaret Doyle, Aliaksei Halavanau +20
We report the successful resolution of the multiplet structure of the Kα1 x-ray emission in manganese (Mn) complexes through seeded stimulated X-ray emission spectroscopy (seeded S…
Attosecond Inner-Shell Lasing at Angstrom Wavelengths
Thomas M. Linker, Aliaksei Halavanau, Thomas Kroll +34
Since the invention of the laser nonlinear effects such as filamentation, Rabi-cycling and collective emission have been explored in the optical regime leading to a wide range of s…
Catalysis in Extreme Field Environments: The Case of Strongly Ionized Nanoparticle Surfaces
Thomas M. Linker, Ritika Dagar, Alexandra Feinberg +8
High electric fields can significantly alter catalytic environments and the resultant chemical processes. Such fields arise naturally in biological systems but can also be artifici…
