High-Power Ultraviolet Vortex Beams Generated from a Relativistic Laser Interacting with an Ultrathin Foil
Conference on Lasers and Electro-Optics（2021）
摘要
Ultrathin foils irradiated by relativistic circularly polarized lasers emit harmonics in both the transmitted and reflected directions that contain orbital angular momentum. We demonstrate this scheme using ab-initio three-dimensional particle-in-cell simulations. (C) 2021 The Author(s)
