Impact of the laser spatio-temporal shape on Breit-Wheeler pair production
A. Mercuri-Baron, M. Grech, F. Niel +4
The forthcoming generation of multi-petawatt lasers opens the way to abundant pair production by the nonlinear Breit-Wheeler process, i.e., the decay of a photon into an electron-p…
Numerical modeling of laser tunneling ionization in Particle in Cell Codes with a laser envelope model
Francesco Massimo, Arnaud Beck, Julien Dérouillat +2
The resources needed for Particle in Cell simulations of Laser Wakefield Acceleration can be greatly reduced in many cases of interest using an envelope model. However, the inclusi…
How to generate intense isolated attosecond pulses from relativistic plasma mirrors?
H. Kallala, F. Quéré, H. Vincenti
Doppler harmonic generation of a high-power laser on a relativistic plasma mirror is a promising path to produce bright attosecond light bursts. Yet, a major challenge has been to…
Efficient cylindrical envelope modeling for laser wakefield acceleration
Francesco Massimo, Imen Zemzemi, Arnaud Beck +2
The resolution of the system given by Maxwell's equations and Vlasov equation in three dimensions can describe all the phenomena of interest for laser wakefield acceleration, with…
Efficient start-to-end 3D envelope modeling for two-stage laser wakefield acceleration experiments
Francesco Massimo, Arnaud Beck, Julien Dérouillat +5
Three dimensional Particle in Cell simulations of Laser Wakefield Acceleration require a considerable amount of resources but are necessary to have realistic predictions and to des…
High-Energy Radiation and Pair Production by Coulomb Processes in Particle-In-Cell Simulations
B. Martinez, M. Lobet, R. Duclous +2
We present a Monte Carlo implementation of the Bremsstrahlung, Bethe-Heitler and Coulomb Trident processes into the particle-in-cell (PIC) simulation framework. In order to address…
