Abstract

We experimentally investigate the angular distribution and the laser intensity dependence of the two-center interference in high-order harmonic generation (HHG) from O2 molecules by comparing with CO2 molecules. Through the measurement of both the temporal evolution and the angular distribution of HHG, the characteristic enhancement and suppression are observed, which can be well explained by the modified interference model. Furthermore, we demonstrate that the spectral region of the constructive enhancement in aligned O2 molecules can be shifted by tuning the driving laser intensity.
