Generation of dense relativistic electron beams via vortex laser-driven self-generated magnetic pinching
Mingxuan Wei, Fengyu Sun, Zhongpeng Li +21
In multi-petawatt laser plasma accelerators, achieving high-density relativistic electron beams is typically accompanied by large transverse divergence, limiting the attainable eff…
Generation of ultra-intense spatiotemporal optical vortex
Renjing Chen, Yilin Xu, Fengyu Sun +5
Spatiotemporal optical vortex (STOV) with transverse orbital angular momentum (TOAM) can induce some novel properties in high energy density physics. However, the current STOV puls…
Enhanced Proton Acceleration via Petawatt Laguerre-Gaussian Lasers
Wenpeng Wang, Xinyue Sun, Fengyu Sun +13
High-energy, high-flux collimated proton beams with high repetition rates are critical for applications such as proton therapy, proton radiography, high-energy-density matter gener…
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-attosecon…
