Orbital angular momentum beam generation using a free-electron laser oscillator

Autor: Liu, Peifan, Yan, Jun, Afanasev, Andrei, Benson, Stephen V., Hao, Hao, Mikhailov, Stepan F., Popov, Victor G., Wu, Ying K.

With wavelength tunability, free-electron lasers (FELs) are well-suited for generating orbital angular momentum (OAM) beams in a wide photon energy range. We report the first experimental demonstration of OAM beam generation using an oscillator FEL.

During the last year we have been benchmarking FEL oscillator simulation codes against the measured performance of the three Jefferson Lab oscillator FELs. While one might think that a full 4D simulation is de facto the best predictor of performance,
