Generation of Isolated Collimated Polarized -ray Beams via Spatiotemporal Optical Vortex Modulation
Xinyu Xie, Fengyu Sun, Huai-Hang Song +2
Attosecond, collimated, bright, polarized -ray sources are in high demand across nuclear physics, astrophysics, and high-energy physics. However, realizing attosecond duration,…
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…
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-attosecond…
