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…

Attosecond electron bunch generation by an intense laser propagation in conical channel with a curved wall
Min Zhang, Cui-Wen Zhang, De-Sheng Zhang +2
By using two-dimensional particle-in-cell simulations, attosecond electron bunches with high density, high energy and small divergence angle can be obtained by p-polarized laser ir…

Generation of -photons and pairs with transverse orbital angular momentum via spatiotemporal optical vortex pulse
Cui-Wen Zhang, De-Sheng Zhang, Bai-Song Xie
We present the generation of well-collimated -photons and pairs with extrinsic transverse orbital angular momentum (TOAM) through the head-on collision of an intense spatiotemp…
