Near cutoff behaviors of high-order harmonic generation from molecular gases
The near cutoff behaviors of high-order harmonic generation (HHG) from molecular gases is investigated. Results reveal that harmonic cutoff is extended only for molecules that show ionization suppression. Another interesting result is that the HHG intensity drops slower in N/sub 2/ and O/sub 2/, while in Ar there is a sharp drop at the cutoff. This phenomena could be induced by the molecule orientation in the laser field.
