Electron Injection and Beam Dynamics in a Laser Wakefield Acceleration Driven by Laser Pulses Carrying Orbital Angular Momentum
Q. Qian, M. Li, Y. Ma +21
Laser pulses carrying orbital angular momentum (OAM) provide a new degree of freedom for controlling plasma-based accelerators. Here, we demonstrate experimentally laser wakefield…

Phase-controlled direct laser acceleration enabled by longitudinal variation of the laser-driven quasi-static plasma magnetic field
R. Bhakta, I-L. Yeh, K. Tangtartharakul +2
Direct laser acceleration (DLA) enables energy transfer from an ultra-high-intensity laser to plasma electrons and underpins many laser-driven particle and radiation-source concept…

Enhanced energy gain through higher-order resonances during direct laser acceleration with superluminal phase velocity
I-Lin Yeh, Kavin Tangtartharakul, Rohan Bhakta +3
Ultra-high intensity laser-plasma interactions can produce ultra-relativistic electrons via direct laser acceleration, assisted by quasi-static plasma magnetic and electric fields.…
