Description
Current multi petawatt laser systems allow unprecedented experimental tests of quantum electrodynamics (QED) in all-optical schemes. In this work we demonstrate experimentally that a single-laser beam Compton scattering arrangement leads to GeV energy photons [Matheron et al. 2024]. The collisions between a reproducible nC, multi-GeV electron beam and the unspent laser by the plasma accelerator via a plasma mirror have a characteristic 100% success rate. The obtained photon energies represent several orders of magnitude increase over the initial seminal results of [Ta Phuoc et al. 2012]. We will discuss the results obtained at Apollon and ELI-NP laser facilities together with their impact for precise investigations of strong-field QED processes and photon sources development.
