The generation of an autoresonantly phase-locked high-amplitude plasma waves to the chirped beat frequency two driving lasers is studied in dimensions using particle-in-cell simulations. two-dimensional and laser parameters correspond those that optimized wave amplitude one-dimensional Near start autoresonant locking, simulations appear similar results (Luo et al. , Phys. Rev. Res. vol. 6, 2024, p. 013338) with amplitudes above Rosenbluth–Liu limit. Later, just below breaking, simulation...
Autoresonant phase locking of the plasma wakefield to beat frequency two driving lasers offers advantages over conventional acceleration methods, since it requires less demanding laser parameters and is robust variations in target density. Here, we investigate kinetic nonlinear processes that come into play during autoresonant beat-wave electrons, their impact on field amplitude accelerating structure, efficiency. Particle-in-cell simulations show process depends density a nontrivial way but...
The effects of incoherence on the three-wave coupling process backward stimulated Raman scattering (SRS) in inhomogeneous plasmas are investigated theoretically and numerically via a model. impact plasma wave nonlinearity is taken into account, namely, effect trapped electrons nonlinear frequency shift electron wave. Incoherence introduced seed wave, laser pump bandwidth associated with Lorentzian power spectrum. It found that temporal can suppress instability as long gain spatial...
Crossed beam energy transfer, CBET, in high-intensity laser-plasma interaction is investigated for the case of optically smoothed laser beams. In two approaches to laser-driven inertial confinement fusion experiments, direct-drive and indirect-drive, CBET great importance because it governs coupling plasma. We use two-dimensional wave-coupling code Harmony simulate transfer between beams with speckle structure that overlap a plasma an inhomogeneous flow profile. compare dynamics spatial...
Previous studies have shown that the use of laser bandwidth may mitigate growth stimulated Raman scattering (SRS) in plasma interaction experiments, particular, when spectrum driving (or pump) is composed uniformly distributed frequency components with a well-chosen [for example, Luo et al., Phys. Plasmas 29, 032102 (2022); Wen ibid. 28, 042109 (2021); and Follett 26, 062111 (2019)]. Here, we investigate effects chirp pump on backward SRS inhomogeneous plasmas, taking into account kinetic...
Abstract The influence of second-order dispersion (SOD) on stimulated Raman scattering (SRS) in the interaction an ultrashort intense laser with plasma was investigated. More significant backward SRS observed increase absolute value SOD ( $\mid \kern-1pt\!{\psi}_2\!\kern-1pt\mid$ ). integrated intensity scattered light is positively correlated to driver pulse duration. Accompanied by side SRS, filaments different angles along propagation direction were transverse shadowgraph. A model...
