Optical metasurfaces with subwavelength thickness hold considerable promise for future
advances in fundamental optics and novel optical applications due to their unprecedented …

Laser-driven plasma-based accelerators, which are capable of supporting fields in excess of
100 GV∕ m, are reviewed. This includes the laser wakefield accelerator, the plasma beat …

The advent of ultraintense laser pulses generated by the technique of chirped pulse
amplification (CPA) along with the development of high-fluence laser materials has opened …

This report presents the conceptual design of a new European research infrastructure
EuPRAXIA. The concept has been established over the last four years in a unique …

An overview is given of the physics issues relevant to the plasma wakefield accelerator, the
plasma beat-wave accelerator, the laser wakefield accelerator, including the self-modulated …

A nonlinear theory of intense laser-plasma interactions is developed and used to describe
relativistic optical guiding, coherent harmonic radiation production, and nonlinear plasma …

The results of an analytical description and of a particle‐in‐cell simulation of the interaction
of an ultrashort, relativistically intense laser pulse, obliquely incident on a nonuniform …

Plasma-based accelerators that impart energy gain as high as several GeV to electrons or
positrons within a few centimeters have engendered a new class of diagnostic techniques …

The investigation of high-order harmonic generation (HHG) of femtosecond laser pulses by
means of laser-produced plasmas is surveyed. This kind of harmonic generation is an …

A novel laser-plasma-based source of relativistic electrons is described. It involves a
combination of orthogonally directed laser beams, which are focused in a plasma. One …
