Abstract

We present a new interpretation of high-order optical harmonic generation (HHG) in atomic gases interacting with laser fields. The mechanism of harmonic generation is due to the temporal evolution of the atomic electron density spatial distribution in the external laser field, and the integral energy of a high harmonic emission and an electron excitation is equal to the work executed by the laser field for an electron motion in the intra-atomic potential field. The proposed interpretation is based on the use of the basis of eigenfunctions of the boundary value problem for “an atom in the external field.” As an illustration, we present the original results of computer simulations of an argon atom interaction with the two-color laser field formed by the fundamental and second harmonics of the Ti:sapphire laser.
