TL;DR: With the current ∼750-nm laser probe and ∼100-eV excitation, the transient recorder is capable of resolving atomic electron dynamics within the Bohr orbit time.

TL;DR: The apparatus allows complete characterization of few-cycle waves of visible, ultraviolet, and/or infrared light, thereby providing the possibility for controlled and reproducible synthesis of ultrabroadband light waveforms.

TL;DR: It is demonstrated that if the emitted electron wave packet is temporally confined to a small fraction of the oscillation period of the interacting light wave, its energy spectrum can be up- or downshifted by many times the laser photon energy without substantial broadening.

TL;DR: In this article, an EUV multilayer mirror with a small spectral bandwidth ΔE≤3 eV at 70 eV peak energy using UHV electron beam evaporation by varying the thickness ratio (Γ=\(\)) between the absorber layer and the bilayer was produced.

TL;DR: Using a laser driven high-harmonic light source, optimized for having the maximum brightness at around 100 eV, a pair of multilayer mirrors to select a narrow spectral band and acting simultaneously as a condenser and a Fresnel zone plate as microscope objective, this paper was able to resolve 200 nm structures of a diatom sample.
