Abstract

At CoReLS a 20 fs, 4 PW Ti:Sapphire laser, constructed in 2017, has been applied for producing multi-GeV electron beams using the laser wakefield acceleration scheme. For the investigation of physical processes in strong-field QED, we explored nonlinear Compton scattering between a multi-GeV electron beam and an ultrahigh intensity laser in an all-optical setup. The gamma-ray signals from the NCS were measured with LYSO scintillation detectors. We could confirm the nonlinear Compton scattering between a GeV electron and several hundred laser photons by obtaining the gamma-ray signal far exceeding the cutoff energy of linear Compton scattering.
