Advanced Shaping of Quasi-Bessel Beams for High-Intensity Applications
Jérôme Touguet, Igor Andriyash, Ronan Lahaye +4
Quasi-Bessel beams produced by axiparabolas are increasingly used in high-intensity laser applications, yet their longitudinal profiles exhibit unwanted oscillations that limit the…

Experimental Demonstration of Dephasing Reduction in an Optically Guided Laser-Plasma Accelerator
Ronan Lahaye, Igor A. Andriyash, Julien Gautier +5
Laser-plasma accelerators offer a compact means of producing high-energy electron beams, but their performance is fundamentally limited by dephasing between the accelerated electro…

Quasi-monoenergetic multi-GeV electron acceleration in a plasma waveguide
Ronan Lahaye, Kosta Oubrerie, Olena Kononenko +3
Laser-plasma accelerators present a promising alternative to conventional accelerators. To fully exploit the extreme amplitudes of the plasma fields and produce high-quality beams,…
