Femtosecond laser technology has attracted significant attention from the viewpoints of
fundamental and application; especially femtosecond laser processing materials present the …

Various basic mechanisms of material surface ablation produced by ultrashort laser pulses
are considered in the order of increasing the supplied laser fluence: low-threshold ultrafast …

Intense femtosecond lasers as well as X-ray free electron lasers provide new means to
produce multiply charged molecular cations. The fragmentation processes that these high …

Recent advances in high-intensity electron and X-ray pulsed sources now make it possible
to directly observe atomic motions as they occur in barrier-crossing processes. These rare …

In the last decade, the development of ultrafast electron diffraction (UED) and microscopy
(UEM) have enabled the imaging of atomic motion in real time and space. These pivotal …

Understanding and actively controlling the spatiotemporal dynamics of nonequilibrium
electron clouds is fundamental for the design of light and electron sources, high-power …

We use femtosecond electron diffraction to study ultrafast lattice dynamics in the highly
correlated antiferromagnetic (AFM) semiconductor NiO. Using the scattering vector (Q) …

We use 30 kV electron pulses to probe transient electric fields above silicon surfaces by
pump-probe. Electron beam deflection at 0.29 mm away from the sample surface on the …
