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…
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…
High-efficient harmonic vortex generation from a laser irradiated hollow-cone target
Ke Hu, Longqing Yi
It has been recently reported that ultraviolet harmonic vortices can be produced when a high-power circular-polarized laser pulse travels through a micro-scale waveguide. However,…
Intense high-harmonic optical vortices generated from a micro-plasma-waveguide irradiated by a circularly polarized laser pulse
Ke Hu, Longqing Yi
A scheme for generating intense high-harmonic optical vortices is proposed. It relies on spin-orbit interaction of light when a relativistically-strong circularly polarized laser p…
