We report on the novel experiment on double ionisation of Helium and Argon in the focus of an 800nm 220fsec laserpulse. We will show recoil ion momentum distribution and electron-electron momentum distributions. These differential data give a detailed insight in the dynamics of strong field sequential and non sequential double ionisation.
