我们研究了载流子包络位相(CEP)标记的少周期激光脉冲对CO的离解电离。我们观察到瞬时CO离子定向发射的CO和O碎片的CEP依赖关系，其中。ATW/cm，来自(，)和(，)通道的CO和O碎片之间的相位差反映了CO电离的取向依赖性。ATW/cm，我们发现来自(，)和()通道的C片段之间有35个相移，这与先前观察到的C片段通道ATW/cm[Phys]之间的移位相反。莱特牧师。106,073004(2011)PRLTAO0031-900710.1103/PhysRevLett.106.073004].
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 Cand Ofragments from transient COions, whereand. AtW/cm, aphase difference between the Cand Ofragments from the (,) and (,) channels reflects the orientation dependence of the CO ionization. AtW/cm, we find a35phase shift between the Cfragments from the (,) and () channels, in contrast to theshift previously observed between the Cfragment channels atW/cm[Phys. Rev. Lett. 106, 073004 (2011)PRLTAO0031-900710.1103/PhysRevLett.106.073004].
