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…
Generation of Polarized Overdense Pair-photon Fireball via Laser-Driven Nonlinear-linear QED Cascade
Zhen-Ke Dou, Qian Zhao, Feng Wan +3
Relativistic, polarized pair-photon fireballs are central to understand the microscopic energy transfer of high-energy astrophysical outflows, yet generating an overdense fireball…
Generation of Ultrabrilliant Positron Beam via Superponderomotive Injection in Laser Wakefield Acceleration
Ting Sun, Zhen-Ke Dou, Ya-Qing Huang +3
Plasma-based acceleration of positrons attracts extensive interest owing to the ultrahigh accelerating gradient and ultrashort duration, while generating wakefield positron beam by…
Ultrafast Spin Rotation of Relativistic Lepton Beams via Terahertz Wave in a Dielectric-Lined Waveguide
Zhong-Peng Li, Yu Wang, Ting Sun +8
Spin rotation is central for the spin-manipulation of lepton beams which, in turn, plays an important role in investigation of the properties of spin-polarized lepton beams and the…
Compact Efficient Polarizers for Relativistic Electron Beams
Kun Xue, Yue Cao, Feng Wan +9
Relativistic spin-polarized electron beams are important for fundamental research and the industry, but their generation currently requires conventional accelerators or ultrastrong…
