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…
Fluorescence intensity correlations enable 3D imaging without sample rotations
Robert G. Radloff, Felix F. Zimmermann, Siqi Li +23
Lensless X-ray imaging provides element-specific nanoscale insights into thick samples beyond the reach of conventional light and electron microscopy. Coherent diffraction imaging…
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…
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…
Shortening X-ray Pulse Duration via Saturable Absorption
Ichiro Inoue, Yuichi Inubushi, Taito Osaka +4
To shorten the duration of x-ray pulses, we present a nonlinear optical technique using atoms with core-hole vacancies (core-hole atoms) generated by inner-shell photoionization. T…
