MOMENTUM SPACE DESCRIPTION OF HYDROGEN ATOM INTERACTING WITH A LOW FREQUENCY, STRONG LASER FIELD

摘要

This short contribution illustrates that the momentum representation is probably the most natural one to describe laser-atom interaction Together with a Wigner function type of analysis, it provides a powerful tool to analyse in detail both the ionisation and harmonic generation dynamics. In particular, this approach looks promising in probing the role of the Coulomb potential during these processes.
