X-ray free-electron lasers, important light sources for materials research, suffer from shot-to-shot fluctuations that necessitate complex diagnostics. Here, the authors apply machine learning to accurately predict pulse properties, using parameters

When exposed to ultraintense x-radiation sources such as free electron lasers (FELs) the innermost electronic shell can efficiently be emptied, creating a transient hollow atom or molecule. Understanding the femtosecond dynamics of such systems is fu

With the development of high power, subpicosecond lasers, it has become possible to study the process of multielectron dissociative ionization of small molecules at intensities in excess of 1014 W cm-2. At such intensities the conventional multiphoto

The maximum electronic charge a molecule can retain when exposed to a static electric field is calculated as a function of internuclear separation. The tendency towards charge-asymmetric fragmentation is modified by introducing an oscillating laser f

The multiphoton ionization of H2 has been studied using laser pulses of 266 nm wavelength, 250 fs duration, and 5x10(13) W/cm(2) peak intensity. Dissociation of H2(+) via one-photon absorption proceeds through two channels with markedly different pro
