摘要：

Information about the time-behavior of high-harmonic generation from a single atom in a strong laser field is obtained through a time-frequency analysis. The solution from the full numerical solution of the time-dependent Schrodinger equation is compared with a widely used two-step semiclassical model of harmonic generation. As a test case, we consider a one-dimensional model ''atom'' with a short-range potential. The two results are in qualitative agreement only if in the two-step model the initial and final (dipole) interaction matrix elements are suitably chosen.
