High-charge, highly polarized positron beams generated from a laser-driven nanowire-array target
De-Sheng Zhang, Cui-Wen Zhang, Kun Xue +4
The generation of high-charge, highly polarized positron beams in the interaction of a linearly polarized laser pulse with a nanowire-array target is investigated. Here, laser-driv…
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…
Electron-positron pair production in spatially inhomogeneous electric fields with quadratically symmetric chirp
Le Le Chen, Xiao-Ting Xu, Rong-An-Tang +3
Electron-positron pair production from vacuum in spatially inhomogeneous electric fields with quadratically symmetric chirp is studied within the real-time Dirac-Heisenberg-Wigner…
Effect of super-Gaussian pulse shape on pair production in chirped electric field with spatial inhomogeneity
Xiao-Ting Xu, Le-Le Chen, Rong-an Tang +3
Pair production in spatially inhomogeneous chirped electric fields with super-Gaussian pulse shape is investigated using the Dirac-Heisenberg-Wigner formalism, and the effect of su…
