Summary of laser plasma physics sessions at the first AAPPS-DPP conference

Abstract

The presentations on laser plasma physics at the first AAPPS-DPP conference covered topics of inertial confined fusion physics and technologies, laboratory astrophysics and high-energy density physics, laser plasma-based particle acceleration (electrons and ions) and radiation, fundamental laser plasma physics, and related high-power laser system development. This report summarizes the major advances in these topics presented at the plenary and oral sessions.

Suppression of parametric instabilities in inhomogeneous plasma with multi-frequency light

“…Laser plasma instabilities [1,2], especially stimulated Raman scattering (SRS), stimulated Brillouin scattering (SBS) and two-plasmon decay (TPD) instability, are among the critical issues, which could prevent the realization of the inertial confinement fusion (ICF) ignition [3,4,5,6,7]. Therefore, the investigation of the fundamental physics and possible suppression strategies about the laser plasma instabilities is necessary [8,9,10,11]. Many ideas have been proposed to suppress parametric instabilities over the last three decades, such as various beam smoothing techniques [12,13], broadband lasers [14,15,16], and external magnetic field [17] etc.…”

The anisotropic plasma wave in the plasma turbulence

“…The laser-plasma interactions and resultant instabilities have been massively investigated both theoretically and experimentally in the past few decades. [30][31][32][33][34][35][36] The effect of such stress has been neglected in the calculation of the growth rate of electromagnetic instability. In the present work, the dispersion characteristics of electromagnetic waves with momentum space anisotropy in the presence of shear stress and body stress have been studied.…”
