Attosecond time delay
By scanning the relative phase of two-color femtosecond lasers, multiple resonance channels in multiphoton ionization of Ar are resolved and channel-specific attosecond time delays are extracted, revealing the influence of resonant phase shifts on photoelectron emission dynamics.
