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…
Decoupling acceleration and wiggling in a laser-produced Betatron source
Julien Gautier, Igor Andriyash, Andreas Döpp +11
Betatron radiation is produced in Laser Plasma Accelerators when the electrons are accelerated and simultaneously wiggle across the propagation axis. The mechanisms of electron acc…
Empirical scaling laws for self-focused laser pulses in nitrogen plasmas
Lorenzo Martelli, Igor Andriyash, Jonathan Wheeler +3
We investigate the interaction between a superintense laser pulse and a nitrogen plasma with densities exceeding cm, using particle-in-cell simulations. Such conf…
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,…
