Observation of Ultrafast Solid-Density Plasma Dynamics Using Femtosecond X-Ray Pulses from a Free-Electron Laser

Physical Review X, 2018
The complex physics of the interaction between short-pulse ultrahigh-intensity lasers and solids is so far difficult to access experimentally, and the development of compact laser-based next-generation secondary radiation sources, e.g., for tumor therapy,

Laser Irradiated Foam Targets: Absorption and Radiative Properties

EPJ Web of Conferences, 2018
An experimental campaign to characterize the laser radiation absorption of foam targets and the subsequent emission of radiation from the produced plasma was carried out in the ABC facility of the ENEA Research Center in Frascati (Rome).

Laser-plasma Interaction and Characterization

The objective of this experiment is to ascertain the ionization degree of laser-generated plasma formed on a carbon target, along with determining the plasma’s expansion velocity. To accomplish these objectives, two distinct methods were employed: shadowgraphy and spectrometry, both widely utilized optical diagnostics in plasma studies.

Global scattered-light spectrography for laser absorption and laser–plasma instability studies

High Power Laser Science and Engineering
An optical spectrometer system based on 60 channels of fibers has been designed and employed to diagnose light emissions from laser–plasma interactions. The 60 fiber collectors cover an integrated solid angle of $\pi$ , enabling the measurement of ...

Production and magnetic self-confinement of e−e+ plasma by an extremely intense laser pulse incident on a structured solid target

Matter and Radiation at Extremes
We propose an all-optical, single-laser-pulse scheme for generating a dense relativistic strongly magnetized electron–positron pair plasma. The scheme involves the interaction of an extremely intense (I ≳ 1024 W/cm2) circularly polarized laser pulse with
