在椭圆偏振周期脉冲引发的碘甲烷强场电离中，观察到激光的载流子包络相位（CEP）与解离双电离产生的甲基阳离子的优先喷射方向之间存在显著的相关性。这是由于载体包络相依赖的碘甲烷的双电离产率。这一观测结果为通过观测离子动量分布来监测少周期脉冲的绝对CEP提供了一种新的方法。
In strong field ionization of methyl iodide initiated by elliptically polarized few-cycle pulses, a significant correlation was observed between the carrier-envelope phases (CEPs) of the laser and the preferred ejection direction of methyl cation arising from dissociative double ionization. This was attributed to the carrier-envelope phase dependent double ionization yields of methyl iodide. This observation provides a new way for monitoring the absolute CEPs of few-cycle pulses by observing the ion momentum distributions.
