From: Anisotropic photoemission time delays close to a Fano resonance

RABBIT measurements obtained with the ETH experimental setup. a Angle-integrated photoelectron spectrum as a function of the XUV-IR delay. b Delay-integrated photoelectron spectrum as a function of the emission angle θ relative to the common axis of polarization of the XUV and IR pulses. c Integration of the spectrogram in angle and delay results in the 1D spectrum where sidebands appear between consecutive harmonics
