| The qualitative behavior of harmonic generation by a collection of atoms is analyzed. Two models are presented, along with calculated harmonic spectra. A comparison of the two models is made.; The first model is semi-classical, based upon the simpleman models of the early nineties. The utility of this model for quickly analyzing complex collections of atoms is demonstrated. Some of the distributions considered include: chains, rings and helices.; The second is a quantum mechanical, zero-range potential model. This model involves a direct numerical integration of the Schrodinger equation. The atomic distribution considered is an infinite chain of regularly spaced atoms. |
