Coincidence measurements of strong field molecular double ionization

We use few cycle intense ultrafast laser pulses and coincidence velocity map imaging to investigate strong field double ionization in molecules. We use a time stamping camera to make vector momentum measurements of electrons and ions, allowing us to distinguish between multiple double ionization channels. Different double ionization channels which result in different fragment ion pairs show different electron correlation patterns, indicating that the double ionization dynamics are influenced by the orbitals from which the electrons are removed.
