We demonstrate high-order harmonic generation in high-density vapors of laser-aligned molecules. Ensembles of aligned CS 2 and N 2 are formed in the focus of a 300 ps duration laser pulse with sufficient density ͑ϳ10 17 molecules cm Ϫ3 ͒ to enable efficient high-order harmonic generation by a second, 70-fs, high-intensity laser pulse. We are able to modulate and significantly enhance the harmonic intensity in aligned molecules compared to the randomly oriented case. Our results are explained bydoi:10.1103/physreva.65.053805 fatcat:xodrg65tjreytkarmb4jahqu5m
