We systematically investigate the contribution of recollision dynamics to the nonsequential double ionization process (NSDI) of Ar atom for a wide range of laser intensity. The result shows that the first- and second-recollision scenarios have significant contribution to the NSDI events. Moreover, we figure out that the impact of double-recollision trajectories decreases as the laser intensity increases. Besides, many details of multiple recollisions are also investigated in this paper.
