TLDR
This work extends bright, spatially coherent, attosecond pulses into the soft x-ray region for the first time and generates the broadest bright coherent bandwidth to date from any light source, small or large, that is consistent with a single subfemtosecond burst.Abstract:
We demonstrate fully phase-matched high harmonic emission spanning the water window spectral region important for nano- and bioimaging and a breadth of materials and molecular dynamics studies. We also generate the broadest bright coherent bandwidth (� 300 eV) to date from any light source, small or large, that is consistent with a single subfemtosecond burst. The harmonic photon flux at 0.5 keV is 10 3 higher than demonstrated previously. This work extends bright, spatially coherent, attosecond pulses into the soft x-ray region for the first time.read more

TL;DR: By guiding a mid-infrared femtosecond laser in a high-pressure gas, ultrahigh harmonics can be generated that emerge as a bright supercontinuum that spans the entire electromagnetic spectrum from the ultraviolet to more than 1.6 kilo–electron volts, allowing, in principle, the generation of pulses as short as 2.5 attoseconds.

The attosecond nonlinear optics of bright coherent X-ray generation
TL;DR: In this paper, the Roentgen X-ray tube was used for high-order harmonic generation with small-scale femtosecond laser technology, which combines the microscopic attosecond science of atoms driven by intense laser fields with the macroscopic extreme nonlinear optics of phase matching.

TL;DR: The results prove that the popular and broadly available scheme of post-compressing the output of white-light-seeded optical parametric amplifiers is adequate to produce high-contrast isolated attosecond pulses covering the L-edges of silicon, phosphorous and sulfur.

TL;DR: Time-resolved x-ray absorption spectroscopy (TR-XAS) has so far practically been limited to large-scale facilities, to subpicosecond temporal resolution, and to the condensed phase, but this realization with a temporal resolution in the low femtosecond range is reported.

Plasma perspective on strong field multiphoton ionization.
TL;DR: During strong-field multiphoton ionization, a wave packet is formed each time the laser field passes its maximum value, and one important parameter which determines the strength of these effects is the rate at which the wave packet spreads in the direction perpendicular to the laser electric field.
Tunnel ionization of complex atoms and of atomic ions in an altemating electromagnetic field
