    Laser-driven plasmas can accelerate electrons in set-ups far smaller than conventional particle accelerators, but beam divergence is a problem. Here, the authors demonstrate a laser-plasma lens that can focus the beam thanks to field gradients five order of magnitude larger than using traditional optics.

    Intense laser pulses can induce the propagation of coherent waves through a plasma, which are useful for accelerating electrons. Here, the authors use a genetic algorithm and a deformable mirror to optimize the wavefront and improve electron beam intensity and divergence.

    Higher beam quality and stability are desired in laser-plasma accelerators for their applications in compact light sources. Here the authors demonstrate in laser plasma wakefield electron acceleration that the beam loading effect can be employed to improve beam quality by controlling the beam charge.

    Extraction of ultra-low emittance bunches is an issue to be addressed for future applications of plasma wakefield accelerators. Here, the authors show that the field structure of the plasma could be suitable for this, by measuring the field's longitudinal variation produced by a relativistic electron bunch.

    High power lasers can produce electron-positron pairs at GeV energies, but doing so through laser–laser collisions would require exceedingly high intensities. Here the authors present an all-optical scheme for pair production by irradiating near-critical-density plasmas with two counter-propagating lasers.

    Table-top laser-plasma ion accelerators have many potential applications, but achieving simultaneous narrow energy spread and high efficiency remains a challenge. Here, the authors produce ion beams with up to 18 MeV per nucleon whilst keeping the energy spread reduced through a self-organized process.

    Plasma wakefield accelerators produce gradients that are orders of magnitude larger than in conventional particle accelerator, but beams tend to be disrupted by transverse forces. Here the authors create an extended hollow plasma channel, which accelerates positrons without generating transverse forces.
