Title: Time-resolved x-ray imaging of a laser-induced nanoplasma and its neutral residuals

Abstract

The evolution of individual, large gas-phase xenon clusters, turned into a nanoplasma by a high power infrared laser pulse, is tracked from femtoseconds up to nanoseconds after laser excitation via coherent diffractive imaging, using ultra-short soft x-ray free electron laser pulses. A decline of scattering signal at high detection angles with increasing time delay indicates a softening of the cluster surface. Here we demonstrate, for the first time a representative speckle pattern of a new stage of cluster expansion for xenon clusters after a nanosecond irradiation. The analysis of the measured average speckle size and the envelope of the intensity distribution reveals a mean cluster size and length scale of internal density fluctuations. Furthermore, the measured diffraction patterns were reproduced by scattering simulations which assumed that the cluster expands with pronounced internal density fluctuations hundreds of picoseconds after excitation.

Figure 1 Figure 1: Schematic diagram of the experimental geometry showing the collinearly incoupled laser beams intersecting the single-cluster beam in the interaction region. An ion time-of-flight spectrometer records the ionized fragments. Scattered photons are collected with a scattering detector comprising of a multi-channel plate (MCP) and a phosphor screen. The phosphormore » screen is imaged with an out-of-vacuum CCD(not depicted here) via a mirror under 45°. Some artefact like dead pixels and decreased detection efficiencies appear in the recorded images which are described in more detail in the supplementary material. Diffraction patterns of individual xenon clusters imaged by soft x-ray scattering reveal the particle size and shape. With the applied source setup a wide size range was produced with the majority of clusters holding a size of 35 nm radius (a) but ranging up to extreme sizes (b)–(d), some even larger than 700 nm in radius (d).« less
