  • Relativistic electron-positron (pair) plasmas play a fundamental role in the magnetospheres, jets, and winds of black holes and neutron stars, but existing studies have been purely theoretical. Here, the authors open up the exciting possibility to probe relativistic pair-plasmas in the laboratory.

  • Electrons can be accelerated by astrophysical shocks if they are sufficiently fast to start with. As laboratory laser-produced shock experiments reveal, this can be achieved by lower-hybrid waves generated by a shock-reflected ion instability.

  • Nonlinear wave mixing has been explored in space plasma. Here the authors report beat-wave Brillouin scattering experiment at EISCAT, in which two radio waves at different transmitted frequencies are driving ion acoustic waves in the ionosphere, leading to stimulated Brillouin emissions escaping the plasma.

  • Plasma Raman amplifiers have been proposed as a mean to increase laser intensity beyond what is currently possible with solid state devices. The paper presents a counterintuitive geometry for a Raman amplifier that allows to optimize the Raman amplification of a seed pulse in a plasma.
