The production of about half of the heavy elements found in nature is assigned to a specific
astrophysical nucleosynthesis process: the rapid neutron-capture process (r process) …

The generation of femtosecond K α x rays from laser-irradiated plasmas is studied with a
view to optimizing photon number and pulse duration. Using analytical and numerical …

Ultrafast x‐ray techniques can, in principle, allow us to more directly watch the time evolution
of matter, with atomic spatial resolution and with time resolution on the scale of atomic …

The production of about half the heavy elements (beyond Fe and Ni) found in nature is
assigned to a specific astrophysical nucleosynthesis process: the rapid neutron capture …

We demonstrate that two harmonic sources generated independently in a xenon gas jet
using the same picosecond Nd: YAG laser are locked in phase. The experiment is …

We have investigated how high-order harmonics generated in rare gases depend on the
atomic density. The peak and the profile of the atomic density in the interaction region were …

We describe experimental studies of high-order harmonic generation in rare-gas-like Na+
and K+ ions. The ions were created in a laser-produced plasma and the harmonics were …

We present an experimental study of harmonic generation in molecular gases, using the
fundamental (800 nm) and the second harmonic (400 nm) of a 150 fs titanium-sapphire laser …

Systematic studies of the temporal coherence properties of high-order harmonic radiation
are presented. These complement our previous investigations [Bellini et al., Phys. Rev. Lett …

We give a theoretical description of the mechanisms underlying the generation of harmonics
of plasma-warming radiation, which depend on the polarization of the latter. We show that …
