Abstract

We present two- and three-dimensional model calculations of high-order harmonic generation in [Formula Presented] The harmonic spectra exhibit clear signatures of intramolecular interference. An interference minimum appears at a harmonic order that depends on the molecular orientation. Harmonic generation in three-center molecules is studied on the basis of two-dimensional calculations for a [Formula Presented] model system. From analytical considerations, the orientation dependence of the harmonic intensities in three-center molecules exhibits a double minimum due to intramolecular interference. In the numerical results, the double minimum is broadened into a single wide minimum. The effect of nonzero laser ellipticity on harmonic generation is investigated by means of two-dimensional simulations for [Formula Presented] We find that harmonic generation with elliptical polarization is governed by interference effects similar to linear polarization.
