Generation of high-energy electron-positron pairs in the collision of a laser-accelerated electron beam with a multipetawatt laser

Autor: M. Lobet, X. Davoine, E. d’Humières, L. Gremillet

Publikováno v: Physical Review Accelerators and Beams, Vol 20, Iss 4, p 043401 (2017)

Generation of electron-positron pairs via the multiphoton Breit-Wheeler process in an all-optical scheme will be made possible on forthcoming high-power laser facilities through the collision of wakefield-accelerated GeV electrons with a counter-prop

Impact of the laser spatio-temporal shape on Breit–Wheeler pair production

Autor: A Mercuri-Baron, M Grech, F Niel, A Grassi, M Lobet, A Di Piazza, C Riconda

Publikováno v: New Journal of Physics, Vol 23, Iss 8, p 085006 (2021)

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–positron pair inside an intense laser field. In this paper we explor

Photonic structuring of perovskite solar cells using opal-like sub-units

Autor: P. Piron, A. Maho, A. Mayer, J. Dewalque, M. Lobet, O. Deparis, C. Henrist, J. Loicq, N. Daem

Publikováno v: Physics and Simulation of Optoelectronic Devices XXIX.

Perovskite solar cells are called to revolutionize the field of optoelectronic due to their intrinsic high absorption. Photonic structuration is widely reported as an efficient way to improve light harvesting. Nevertheless, little is known on the com

International audience; Particle-In-Cell (PIC) codes are broadly applied to the kinetic simulation of plasmas, from laser–matter interaction to astrophysics. Their heavy simulation cost can be mitigated by using the Single Instruction Multiple Data

Soon available multi petawatt ultra-high-intensity (UHI) lasers will allow us to probe high-amplitude electromagnetic fields interacting with either ultra-relativistic electron beams or hot plasmas in the so-called moderately quantum regime. The corr
