Helical Electron Beam Micro-Bunching by High-Order Modes in a Micro-Plasma Waveguide
Xinju Guo, Longqing Yi
Electron acceleration by a high-power Laguerre-Gaussian pulse in a micro-plasma waveguide is investigated. When the incident laser travels in the waveguide, electrons on the wall a…

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…

Anomalous Effects in Single-slit Diffraction of Light at Relativistic Intensities
Longqing Yi
High-order harmonic generation via single-slit diffraction of relativistic laser pulses is investigated. Using fully kinetic 2D and 3D particle-in-cell simulations, we show that in…
