As an intense few-cycle pulse interacts with an atomic or molecular target, its strong oscillating field may first pull electrons out of the target and subsequently drive them back to scatter on the target. The scattering may occur only a few times or even once during the interaction. This unique property of few-cycle pulses enables one to image ultrafast transient structures of matter by the means of pulse-driven electron diffraction. We demonstrated this phenomenon with K-2(+) via three-dimensional calculations of the time-dependent Schrodinger equation.
