Some of the basic mechanisms governing the physics of the processes occuring when atoms are exposed to intense infrared laser pulses, with peak intensities higher then 1014 W/cm2 are considered. Special attention is devoted to the actual role of the Coulomb potential in the ejection of electrons of low energy (less than twice the ponderomotive potential). To this end, we study the time evolution of the wavefunction by solving numerically the time‐dependent Schrödinger equation for atomic hydrogen in momentum space. Our results clearly show that it is possible to identify two distinct ionization mechanisms characterized by the emission of “direct” and “indirect” wavepackets in clear contrast with the predictions of the well established strong field approximation.
