Relativistic Oscillating Window Driven by an Intense Laguerre-Gaussian Laser Pulse
Author(s): Yao Meng, Runze Li, and 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 dynamics at the boundary of the diffraction aperture can facilitate complex interplay between the spin and orbital angula… [Phys. Rev.
