From: Nonsequential double ionization with mid-infrared laser fields
Left column (a,c): Statistical distributions of the time difference (tr − tSI), i.e., the time difference between successful recollision and emission of the first electron, for two wavelengths and two laser intensities as labeled on the figure. Right column (b,d): Statistical difference of the time difference (tDI − tr), i.e., the time difference between complete double ionization and recollision, for the same two wavelengths and laser intensities.
