Measuring strong-field ionization electron holograms

I will discuss our latest results using velocity map imaging to explore the motion of electrons in molecules ionized by intense laser fields.  We combine several experimental methods: High-fidelity velocity map imaging can reveal small details in the complex momentum-space interference patterns formed by the electrons.  The dependence of these patterns on sub-cycle features in the shape of the strong laser field can be studied by combining the strong laser pulse with its own harmonics.   This field-shape dependence of the VMI patterns provides attosecond temporal information about the ionization process.  We also employ time-filtering methods on the data, which allow us to separate sub-cycle dynamics from the dominant above-threshold ionization features in the momentum map.
