TLDR
In this article, the synchronization between individual pulses of the femtosecond extreme ultraviolet (XUV) free electron laser in Hamburg and an independent intense 120fs mode-locked Ti:sapphire laser was analyzed.Abstract:
Two-color above threshold ionization of helium and xenon has been used to analyze the synchronization between individual pulses of the femtosecond extreme ultraviolet (XUV) free electron laser in Hamburg and an independent intense 120fs mode-locked Ti:sapphire laser. Characteristic sidebands appear in the photoelectron spectra when the two pulses overlap spatially and temporally. The cross-correlation curve points to a 250fs rms jitter between the two sources at the experiment. A more precise determination of the temporal fluctuation between the XUV and infrared pulses is obtained through the analysis of the single-shot sideband intensities.read more

TL;DR: In this paper, the authors present pump probe experiments with femtosecond time resolution using free electron laser (FEL) facilities. And they provide the ideal targets for early experiments by which not only FELs can be characterised and benchmarked but can also be the natural departure point in the hunt for non-linear behaviour of atomistic systems bathed in laser fields of ultrahigh photon energy.

High interannual variability of sea ice thickness in the Arctic region.
TL;DR: An eight-year time-series of Arctic ice thickness is used, derived from satellite altimeter measurements of ice freeboard, to determine the mean thickness field and its variability from 65° N to 81.5° N, which reveals a high-frequency interannual variability in mean ArcticIce thickness that is dominated by changes in the amount of summer melt, rather than byChanges in circulation.
