High-Harmonic Optical Vortex Generation from a Plasma Aperture
Runze Li, Wenchao Yan, Longqing Yi
When a high-power, femtosecond, circularly polarized (CP) laser pulse is incident on a micrometer-scale aperture in a solid foil target, it drives surface plasma oscillation, gener…

Relativistic Oscillating Window Driven by an Intense Laguerre Gaussian Laser Pulse
Yao Meng, Runze Li, Longqing Yi
High-order harmonic generation by the diffraction of an intense Laguerre-Gaussian (LG) laser beam through a small aperture is studied. It is found that the 2D peripheral electron d…
