Abstract
We report a joint experimental and theoretical study of a three-sideband (3-SB) modification of the “reconstruction of attosecond beating by interference of two-photon transitions” (RABBIT) setup. The 3-SB RABBIT scheme allows to investigate phases resulting from the interference between transitions of different orders in the ionization continuum. The strength of this method is its ability to focus on the angle-dependent atomic phases only, independent of a possible spectral chirp of the exiting EUV fields. Furthermore, with a traditional 1-SB RABBITT scheme, we observe an asymmetry of the electron emission direction with respect to the proton after few-photon dissociation of molecular hydrogen and present sub-femtosecond control of this emission direction.
