Single-shot carrier envelope phase (CEP) tagging has been utilized in a cold-target recoil-ion momentum spectroscopy (COLTRIMS) measurement of ultra-short laser-induced non-sequential double ionization (NSDI) of argon. This novel technique facilitates an unprecedented level of stability, longevity, and precision in the determination of CEP dependence and, in general, shows great promise for utilization in a wide variety of CEP sensitive measurements. Here we find that the yield of Ar2+ in 4 fs laser fields at 750 nm and an intensity of 1.6×1014 W/cm2 shows a strong CEP dependence which compares with recent theoretical predictions employing quantitative rescattering (QRS) theory. Additionally, the Ar2+ momentum, along the laser polarization axis, is strongly influenced by the CEP.
