Using an apparatus that images the momentum distribution of individual, isolated 100-nm-scale plasmas, we make the first experimental observation of shock waves in nanoplasmas. We demonstrate that the introduction of a heating pulse prior to the main laser pulse increases the intensity of the shock wave, producing a strong burst of quasimonoenergetic ions with an energy spread of less than 15%. Numerical hydrodynamic calculations confirm the appearance of accelerating shock waves and provide a…

Ultrafast Structural Dynamics of Nanoparticles in Intense Laser Fields.

TLDR
Using wide-angle scattering with intense femtosecond x-ray pulses from a free-electron laser source, it is found that highly excited xenon nanoparticles retain their crystalline bulk structure and density in the inner core long after the driving NIR pulse.

Optimizing laser-driven proton acceleration from overdense targets

We demonstrate how to tune the main ion acceleration mechanism in laser-plasma interactions to collisionless shock acceleration, thus achieving control over the final ion beam properties (e. g.

Electronic oscillations in ionized sodium nanoclusters

Irradiation of nanosized metallic clusters by femtosecond laser pulses of moderate intensities ( 10 12 – 10 14 W cm − 2 ?> ) leads to creation of the so-called electron–ion nanoplasma with

Relaxation and collective excitations of cluster nano-plasmas

Nano-plasmas produced, for example, in clusters after short-pulse laser irradiation, can show collective excitations, as derived from the time evolution of fluctuations in thermodynamic equilibrium.

Autoionization following nanoplasma formation in atomic and molecular clusters

Abstract Nanoplasmas resulting from the ionization of nano-scale particles by intense laser pulses are typically described by quasiclassical models, where electron emission is understood to take

Mapping nanoscale absorption of femtosecond laser pulses using plasma explosion imaging.

TLDR
Four different nanoparticle samples with overall dimensions of ∼100 nm are studied and find that each sample exhibits distinct light absorption mechanisms despite their similar size, which demonstrates the diverse ways in which nanoparticles respond to strong laser fields.

Plasma channel formation in NIR laser-irradiated carrier gas from an aerosol nanoparticle injector

TLDR
The results indicate that field ionisation by the intense near-infrared laser pulse opens up a plasma channel behind the laser pulse, and can be understood in terms of a Coulomb explosion of the created underdense plasma channel.

Field propagation-induced directionality of carrier-envelope phase-controlled photoemission from nanospheres

Near-fields of non-resonantly laser-excited nanostructures enable strong localization of ultrashort light fields and have opened novel routes to fundamentally modify and control electronic

Direct observation of enhanced electron-phonon coupling in copper nanoparticles in the warm-dense matter regime

Warm-dense matter (WDM) represents a highly-excited state that lies at the intersection of solids, plasmas, and liquids and that cannot be described by equilibrium theories. The transient nature of

Femtosecond and nanometre visualization of structural dynamics in superheated nanoparticles

Single Xe clusters are superheated using an intense optical laser pulse and the structural evolution is imaged with a single X-ray pulse. Ultrafast surface softening on the nanometre scale is
