Multicolour above-threshold ionization of helium : Quantum interference effects in angular distributions
(2005) In Journal of Physics B: Atomic, Molecular and Optical Physics 38(22).- Abstract
Energy- and angle-resolved photoionization spectra of He irradiated by linearly polarized intense 810 nm laser radiation and several of its XUV odd harmonics are investigated. The angular distribution of the odd-order peaks, produced by single-photon ionization by one harmonic, is, surprisingly, broadened by the IR field. The even-order ones, due to two-colour, two-photon ionization, show at 90° lobes which depend on the relative IR-XUV phase. Application to the characterization of attosecond pulses is suggested.
