Zusammenfassung	We explore the dissociative ionization of CO with carrier-envelope-phase (CEP) tagged few-cycle laser pulses. We observe the CEP dependence of the directional emission of C^p+ and O^q+ fragments from transient CO^(p+q)+ ions, where p+q≤3 and q≤1. At I₀=3.5×10¹⁴ W/cm², a 180° phase difference between the C⁺ and O⁺ fragments from the (p=1, q=0) and (p=0, q=1) channels reflects the orientation dependence of the CO ionization. At I₀=1.2×10¹⁵ W/cm², we find a appr. 35° phase shift between the C²⁺ fragments from the (p=2, q=0) and (p=2, q=1) channels, in contrast to the 180° shift previously observed between the C²⁺ fragment channels at I₀=6×10¹⁴ W/cm² [ Phys. Rev. Lett. 106 073004 (2011)].
