Presented are the carrier-envelope phase (CEP) and energy dependent ATI spectra for Xenon, Argon, and Neon. This data was obtained using a phase tagging technique which is based on a novel, robust, real-time, every-single-shot technique for determining the carrier-envelope phase via a stereographic ATI setup. The CEP is calculated and output within ∼20 µs of the laser interaction and this information is then used to tag ATI data of several noble gases to investigate their dependence on the relative CEP. Additionally the relative phase was kept constant for all targets, thus the relationship between the ATI phase dependencies is revealed. This phase measurement also enables the tagging of any other event-mode experiment run in parallel with the phase determination to get a relative dependence of these experiments from the corresponding CEP of the pulse.
