Description
We theoretically and experimentally demonstrate the generation of attosecond vortex pulse trains, i.e. a succession of attosecond pulses with a helical wavefront, resulting from the coherent superposition of a comb of high-order harmonics carrying the same orbital angular momentum (OAM)[1]. The control of spin and OAM degrees of freedom in extreme ultraviolet attosecond pulses brings new capabilities to spectroscopic and imaging applications in chiral and magnetic systems.
