Angular Distribution of High Harmonic Generation in Aligned CO₂ Molecules

Abstract:

We investigate the angular distribution of high harmonic generation (HHG) from impulsively aligned CO2 molecules driving by the femtosecond laser. We first observe the HHG spectra under the different aligning angles and the different laser intensities. The angular distribution is found to be sensitive to both the harmonic order and the intensity of the driving laser pulse. At last, we theoretically and experimentally demonstrate the angular distribution with the different harmonic orders and the different laser intensities.
