Liu C, Shen B, Zhang X, Shi Y, Ji L, Wang W, Yi L, Zhang L, Xu T, Pei Z, Xu Zet al., 2016, Generation of Gamma-ray Beam with Orbital Angular Momentum in the QED Regime, Physics of Plasmas, Vol: 23, ISSN: 1070-664X

We propose a scheme to generate high-energy gamma-ray photons with an orbital angular momentum(OAM) from laser-plasma interactions by irradiating a circularly polarized Laguerre–Gaussianlaser on a thin plasma target. The spin angular momentum and OAM are first transferred toelectrons from the driving laser, and then the OAM is transferred to the gamma-ray photonsfrom the electrons through quantum radiation. This scheme has been demonstrated by usingthree-dimensional quantum electrodynamics particle-in-cell simulations. The topological charge,chirality, and carrier-envelope phase of the short ultra-intense vortex laser can be revealedaccording to the energy distribution of gamma-ray emission.

An interesting deflection effect deviating the optical reflection law is revealed in the relativistic regime ofintense vortex laser plasma interaction. When an intense vortex laser obliquely impinges onto an overdenseplasma target, the reflected beam deflects out of the plane of incidence with an experimentally observabledeflection angle. The mechanism is demonstrated by full three-dimensional particle-in-cell simulation aswell as analytical modeling using the Maxwell stress tensor. The deflection results from the rotationalsymmetry breaking of the foil driven by the unsymmetrical shear stress of the vortex beam.The l-dependent shear stress, where l is the topological charge, as an intrinsic characteristic to the vortexbeam, plays an important role as the ponderomotive force in relativistic vortex laser matter interaction.
