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 .

High-energy $$\gamma$$ -photons and pair electrons generation in polarized ultraintense laser fields [PDF]

Scientific Reports
We demonstrate the generation of high-energy $$\gamma$$ -photons and pair electrons resulting from the interaction of an ultrahigh-intensity laser pulse with a near-critical density plasma target.

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 ...

Laser–plasma interactions for fast ignition [PDF]

Nuclear Fusion, 2014
In the electron-driven fast-ignition approach to inertial confinement fusion, petawatt laser pulses are required to generate MeV electrons that deposit several tens of kilojoules in the compressed core of an imploded DT shell. We review recent progress in the understanding of intense laser plasma interactions (LPI) relevant to fast ignition.

Investigation of Plasma Formation with ns Laser by Using Focused Sub-ns Laser Probe

EPJ Web of Conferences, 2018
A laser ablation plasma formation process was investigated by shooting another laser beam. The initial plasma was created by a mildly focused nanosecond laser beam and the probe laser, which has about ten times shorter pulse length with tightly focussed ...

Impacts of Ambient and Ablation Plasmas on Short- and Ultrashort-Pulse Laser Processing of Surfaces

Micromachines, 2014
In spite of the fact that more than five decades have passed since the invention of laser, some topics of laser-matter interaction still remain incompletely studied. One of such topics is plasma impact on the overall phenomenon of the interaction and its

Radiation sources based on laser–plasma interactions [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2006
Plasma waves excited by intense laser beams can be harnessed to produce femtosecond duration bunches of electrons with relativistic energies. The very large electrostatic forces of plasma density wakes trailing behind an intense laser pulse provide field potentials capable of accelerating charged particles to high energies over very short distances, as
