Investigation on the origin of hot electrons in laser plasma interaction at shock ignition intensities [PDF]

Scientific Reports, 2023
Shock Ignition is a two-step scheme to reach Inertial Confinement Fusion, where the precompressed fuel capsule is ignited by a strong shock driven by a laser pulse at an intensity in the order of $$10^{16}$$ 10 16 W/cm $$^2$$ 2 .

Stable and tunable MeV $$\gamma$$ -ray generation via dual-laser inverse Thomson scattering from a laser-plasma accelerator [PDF]

Scientific Reports
Inverse Thomson scattering from laser-plasma accelerators offers a pathway to compact, tunable MeV $$\gamma$$ -ray sources for reduced-dose radiography and enhanced performance in nuclear resonance fluorescence (NRF)-based isotope identification. However,

New Spectral Range Generations from Laser-plasma Interaction

مجلة بغداد للعلوم, 2021
High-intensity laser-produced plasma has been extensively investigated in many studies. In this demonstration, a new spectral range was observed in the resulted spectra from the laser-plasma interaction, which opens up new discussions for new light ...

Shock interactions between plasma jets from conical wire array Z-pinches and laser-produced plasma plume

Results in Physics, 2022
The interaction of a supersonic plasma jet outflow with a background laser-produced plasma plume is experimentally studied. The aim of these studies is to provide an experimental platform to study jet-ambient interactions in an environment relevant to ...

Off-harmonic optical probing of high intensity laser plasma expansion dynamics in solid density hydrogen jets

Scientific Reports, 2022
Due to the non-linear nature of relativistic laser induced plasma processes, the development of laser-plasma accelerators requires precise numerical modeling.

Laser-plasma interactions in magnetized environment [PDF]

Physics of Plasmas, 2018
Propagation and scattering of lasers present new phenomena and applications when the plasma medium becomes strongly magnetized. With mega-Gauss magnetic fields, scattering of optical lasers already becomes manifestly anisotropic. Special angles exist where coherent laser scattering is either enhanced or suppressed, as we demonstrate using a cold-fluid ...
