Abstract
Double ionization in intense laser fields can comprise electron correlations which manifest in the nonindependent emission of two electrons from an atom or molecule. However, experimental methods that directly access the electron emission times have been scarce. Here we explore the application of an all-optical streaking technique to strong-field double ionization, both theoretically and experimentally. We show that both sequential and nonsequential double-ionization processes lead to streaking delays that are distinct from each other and single ionization. Moreover, coincidence detection of ions and electrons provides access to the emission time difference, which is encoded in the two-electron momentum distributions. The experimental data agree very well with simulations of sequential double ionization. We further test and discuss the application of this method to nonsequential double ionization, which is strongly affected by the presence of the streaking field.
