Abstract
Attosecond time-resolved photoelectron spectroscopy reveals photoemission dynamics, for example, via reconstruction of attosecond beating by interference of two-photon transitions (RABBITT). However, the multitude of photoemission peaks in a RABBITT spectrogram often limits the applicability of the method to well-separated photoemission channels. Here, we derive relations between RABBITT oscillations of sidebands and principal bands within strong field approximation. This allows extracting timing information on the photoemission dynamics for rather convoluted RABBITT spectra, for which the common analysis would fail. This improvement is demonstrated for simulated overlapping RABBITT spectrograms based on a solid-state photoemission model showing the robust reconstruction of the individual photoemission delays.
