Polarization-resolved attosecond gamma-ray emission from few-cycle laser interactions with cone targets
De-Sheng Zhang, Cui-Wen Zhang, Xue-Ren Hong +3
Linearly polarized attosecond -ray pulses in the MeV range are generated from a cone target irradiated by a single few-cycle laser pulse. Electron layers are periodically extrac…

Generation-Resolved Signatures in QED Cascades: Diagnostics for Ultraintense Laser Parameters
Ke-Jia Wei, Feng Wan, Hao-Tian Wang +3
We present a generation-resolved analysis of shower-type, spin- and polarization-dependent quantum electrodynamics (QED) cascades initiated by head-on collisions of ultraintense la…
