Conférence de Christos Kamperidis

rss

Christos Kamperidis, group leader, Electron Acceleration Group à ELI Attosecond Light Pulse Source en Hongrie, présentera une conférence le 26 juin 2017 à 11 h, à la salle de conférence Tudor Johnston du Centre Énergie Matériaux Télécommunications de l'INRS à Varennes. Christos Kamperidis est l'invité du professeur François Légaré.  

La conférence de Christos Kamperidis s'intitule « Laser wakefield acceleration with high power, few-cycle mid-IR lasers ».

 

 

Summary:

The study of laser wakefield electron acceleration (LWFA) using mid-IR laser drivers is a promising path for future laser driven electron accelerators, when compared to traditional near-IR laser drivers operating at 0.8 - 1 μm central wavelength (λlaser), as the necessary vector potential (a0) for electron injection can be achieved with smaller laser powers due to the linear dependence on λlaser. In this work, we perform 2D PIC simulations on LWFA using few-cycle, high power laser systems with λlaser ranging from 0.8 to 3.2 μm. Such few-cycle systems are currently under development, aiming at Gas High Harmonics Generation applications, where the favourable λ2laser scaling extends the range of the XUV photon energies. We keep a0 and ne/ncr (ne being the plasma density and ncr the critical density for each λlaser) as common denominators in our simulations, allowing for comparisons between laser drivers with different λlaser, with respect to accelerated electron beam charge, energy and conversion efficiency.
