TL;DR: It is shown that, by using a compact laser-driven setup, ion-free electron–positron plasmas with unique characteristics can be produced, and their charge neutrality, high-density and small divergence finally open up the possibility of studying electron– Positron Plasmas in controlled laboratory experiments.

TL;DR: The first experimental demonstration of saturable absorption in core-electron transitions in aluminium paves the way for investigating warm dense matter, which potentially has an important role in planetary science and the realization of inertial confinement fusion.

TL;DR: This work demonstrates experimentally the key influence of the steepness of the plasma-vacuum interface on the interaction, by measuring the spectral and spatial properties of harmonics generated on a plasma mirror whose initial density gradient scale length L is continuously varied.

TL;DR: Theoretical studies have predicted an alternative regime in which short-wavelength light is generated by dense electron nanobunches that form at the plasma-vacuum boundary as discussed by the authors.

TL;DR: It is demonstrated for the first time that dense relativistic electron mirrors can be created from the interaction of a high-intensity laser pulse with a freestanding, nanometre-scale thin foil.
