High-Harmonic Generation and Optical Torque Interaction via Relativistic Diffraction of a Spatiotemporal Vortex Light
Ke Hu, Xinju Guo, Longqing Yi
Diffraction of a relativistically-strong light can produce high-order harmonics via the relativistic oscillating window mechanism. In this process, the characteristics of the 2D el…

Generation of isolated attosecond electron bunches by the diffraction of a polarization-tailored intense laser beam
Ke Hu, Longqing Yi
We propose utilizing a polarization-tailored high-power laser pulse to extract and accelerate electrons from the edge of a solid foil target to produce isolated attosecond electron…
