TL;DR: In this paper, counterstreaming plasmas were produced by ablating plasma from the inside surfaces of two parallel disks made of aluminum and magnesium, respectively, with a 0.53 μm laser at an intensity of 1014 W/cm2 for 1.3 nsec.

TL;DR: Two-dimensional Vlasov simulations of nonlinear electron plasma waves are presented in this paper, in which the interplay of linear and nonlinear kinetic effects is evident, and the quasisteady distribution of trapped electrons and its self-consistent plasma wave are studied after the external field is turned off.

TL;DR: It is found that the shared electron plasma wave (EPW) process, where the lasers collectively drive the same EPW, can lead to an absolute instability when the electron density reaches a matching condition dependent on the cone angle of the laser beams.

TL;DR: In this paper, a hydrodynamic model was developed that allows interpenetration but explicitly converts kinetic energy into heat as the ions slow down, which is applied to the collision of two plasmas created by heating two parallel foils.

TL;DR: Numerical simulations show that the energy transfer between beams can be tuned to redistribute the energy within the cones of beams most prone to backscatter instabilities, and could significantly reduce stimulated Raman scattering losses and increase the hohlraum radiation drive while maintaining a good implosion symmetry.
