Abstract

We present a theoretical approach of high-order harmonic generation (HHG) in polyatomic molecules based on the strong-field approximation (SFA) and within the frame of the single electron approximation. Our model allow us to turn on and off contributions having distinct physical origins or corresponding to different physical mechanisms. Results in di- and triatomic systems are shown. In addition a time-frequency analysis is presented to investigate the relative weight of the different electron trajectories contributing to the HHG spectra.
