Isolated Attosecond -Ray Pulse Generation with Transverse Orbital Angular Momentum Using Intense Spatiotemporal Optical Vortex Lasers
Fengyu Sun, Xinyu Xie, Wenpeng Wang +5
An isolated attosecond vortex -ray pulse is generated by using a relativistic spatiotemporal optical vortex (STOV) laser in particle-in-cell simulations. A 300-attosecond…
