Photoelectron Holography: Exploration of the Multiphoton Ionization and Multiple Rescattering in Intense Laser Fields

We perform a fully ab initio investigation of the multiphoton ionization (MPI) and electron multiple rescattering dynamics of atomic H driven by intense ultrashort mid-IR laser fields. The time-dependent Schr\"{o}dinger equation is solved accurately and efficiently by means of the time-dependent generalized pseudospectral method (TDGPS) in the Kramers-Henneberger (KH) frame. We use the semiclassical approach to analyze and visualize all the trajectories during the atom-laser interaction, unveiling the multiple e-parent ion rescattering processes. In this way, we can identify the dominant behaviors of different parts of photoelectron holography to a particular number of times of the electron's revisits to its parent ion.
