Following the advent of petawatt (PW)-class lasers already capable of achieving light
intensities of 10 23 W/cm 2, high-field science now aims at solving a major challenge of …

The quantum vacuum plays a central role in physics. Quantum electrodynamics (QED)
predicts that the properties of the fermionic quantum vacuum can be probed by extremely …

with a solid target Page 1 J. Plasma Phys. (2022), vol. 88, 905880104 © The Author(s), 2022 …

We use large scale, three-dimensional particle-in-cell simulations to demonstrate that a high-
quality energetic ion beam can be stably generated by irradiation of a multi-species nanofoil …

Backward Raman amplification of laser pulses in plasmas can produce nearly relativistic
unfocused output intensities and multi-exawatt powers in compact devices. The largest …

We have previously shown that laser light can be upshifted to higher frequencies by its
reflection off relativistically moving mirrors in plasma. These mirrors were generated with …

Collision between relativistic electron sheets and counterpropagating laser pulses is
recognized as a promising way to produce intense attosecond x rays through coherent …

The leading amplified spike in backward Raman amplifiers can reach nearly relativistic
intensities before the saturation by the relativistic electron nonlinearity. The saturation sets …

In the wake of steady progress in laser technology opening up to an ever wider range of
physical configurations, a consistent research community developed around “ultra-high …

Manipulation of laser pulses at high intensities is an important yet challenging issue. New
types of plasma-based optical devices are promising alternatives to achieve this goal. Here …
