Figures & Tables

Fig. 1. (Color online) (a) Schematic illustration of the overlapping of an IAP (red line) with an IR pulse: time instants t1 and t2 determine the IAP, while t3 and t4 determine the IR pulse. (b) A typical electric field pattern of the overlapped IAP and the IR pulse, for which three categories of circles are defined: the inner circle, the intermediate circles, and the outer circle. IIR=2×1014 W/cm2, IIAP=8×1011 W/cm2.
