Helium nanodroplets irradiated by intense near-infrared laser pulses ignite and form highly ionized nanoplasmas even at laser intensities where helium is not directly ionized by the optical field, provided the droplets contain a few dopant atoms. We present a combined theoretical and experimental study of the He nanoplasma ignition dynamics for various dopant species. We find that the efficiency of dopants to ignite a nanoplasma in helium droplets strongly varies and mostly depends on (i) the… 

Charging dynamics of dopants in helium nanoplasmas

Abstract We present a combined experimental and theoretical study of the charging dynamics of helium nanodroplets doped with atoms of different species and irradiated by intense near-infrared laser

Dopant-induced ignition of helium nanoplasmas—a mechanistic study

Helium (He) nanodroplets irradiated by intense near-infrared laser pulses form a nanoplasma by avalanche-like electron impact ionizations (EIIs) even at lower laser intensities where He is not

Comparison of Electron and Ion Emission from Xenon Cluster-Induced Ignition of Helium Nanodroplets.

The charging dynamics of helium droplets driven by embedded xenon cluster ignition in strong laser fields is studied by comparing the abundances of helium and highly charged Xe ions to the electron signal, indicating differences in the temporal and spacial development of the charge state distribution of Xe core and He surrounding.

We explore the light induced dynamics in superfluid helium nanodroplets with wide-angle scattering in a pump–probe measurement scheme. The droplets are doped with xenon atoms to facilitate the

Phase-of-the-Phase Electron Momentum Spectroscopy on Single Metal Atoms in Helium Nanodroplets.

Magnesium atoms fully embedded in helium nanodroplets are exposed to two-color laser pulses, which trigger multiphoton above-threshold ionization (ATI). This allows exemplary study of the

A source to deliver mesoscopic particles for laser plasma studies.

The development of a delivery mechanism of microparticles into an effusive jet in vacuum for laser plasma studies is outlined and the first results of x-ray emission from micro crystals of boric acid that extends to 100 keV even under relatively mild intensities are presented.

Dynamics of Photoexcited Cs Atoms Attached to Helium Nanodroplets.

The results suggest that the dynamics following excitation to the 6p 2Π3/2 state can be described by an evaporation-like desorption mechanism, whereas the dynamics arising from excitation from the 6 p 2Σ1/2state is indicative for a more impulsive Desorption process.



Dopant-induced ignition of helium nanodroplets in intense few-cycle laser pulses.

It is found that less than 10 dopant atoms "ignite" the droplet to generate a nonspherical electronic nanoplasma resulting ultimately in complete ionization and disintegration of all atoms, although the pristine He droplet is transparent for the laser intensities applied.

Laser-driven nanoplasmas in doped helium droplets: local ignition and anisotropic growth.

Doping a helium nanodroplet with only a tiny xenon cluster of a few atoms sparks complete ionization of the droplet at laser intensities below the ionization threshold of helium atoms. As a result,

The plasma dynamics of single mesoscopic Xe particles irradiated with intense femtosecond x-ray pulses exceeding 10(16)  W/cm2 from the Linac Coherent Light Source free-electron laser are investigated and show that for clusters illuminated with intense x-Ray pulses, highly charged ionization fragments in a narrow distribution are created.
