Non-sequential Double Ionization (NSDI) of atoms in strong laser fields has been the subject of numerous experimental and theoretical studies. Yet, the mechanisms that govern this process are not fully understood. Advances in ultra-fast lasers technology have permitted the generation of light pulses with a duration close to a single optical cycle, which can be used to study quantum dynamics with attosecond time resolution. Using a reaction microscope in combination with the recently developed single-shot Carrier-Envelope-Phase (CEP) measurement technique, we investigate the sub-cycle dynamics of the NSDI process in Argon atoms exposed to near single-cycle laser pulses. Measurements of CEP-resolved two-electron coincidence spectra of NSDI are presented and discussed.
