Phase-locked laser-wakefield electron acceleration
Phase-locked laser-wakefield electron acceleration A Laser-Plasma Accelerator (LPA) uses accelerating fields (wakefield) that are typically 3 orders of magnitude higher than in radio-frequency accelerators. These extreme fields could allow for
Two color soft x-ray laser
Two colors soft x-ray laser X and soft X-ray coherent sources are widely used tools to probe ultrafast dynamics of the matter on the nanometer scale. Among many of their

André Antonetti nous a quitté ce lundi 13 avril 2020, emporté par le coronavirus, à l’âge de 88 ans. Le Laboratoire d’Optique Appliquée où il a passé toute sa carrière
Relativistic-intensity 1.5-cycle light waveforms at kHz repetition rate
The development of ultra-intense and ultra-short light sources is currently a subject of intense research driven by the discovery of novel phenomena in the realm of relativistic optics, such as
Structured Plasma Boosts X-Ray Flux
High-intensity sources of femtosecond x-ray pulses are a must-have tool for studying ultrafast processes. Unfortunately, only a handful of kilometer-long free-electron lasers can produce these pulses, making them inaccessible to
Tunable high spatio-spectral purity undulator radiation from a transported laser plasma accelerated electron beam
Undulator based synchrotron light sources and free electron Lasers (feLs) are valuable modern probes of matter with high temporal and spatial resolution. Laser Plasma Accelerators (LPAs), delivering GeV electron beams in
EPS Hannes Alfvén Prize 2019
EPS Hannes Alfvén Prize 2019 for outstanding contributions to plasma physics awarded to Victor Malka, of the Laboratoire d’Optique Appliquée (LOA – CNRS/ENSTA-ParisTech/Ecole Polytechnique) Edited January 10th, 2019 The EPS Hannes
A laser-plasma tool to reduce the drag experienced by a supersonic objec
When a body moves in the atmosphere with a supersonic velocity, a shock wave is generated. This leads to a considerable increase in the drag experienced by the supersonic object
