Controlling the interference of multiple molecular orbitals in high-harmonic generation.
We demonstrate a new method to investigate the origin of spectral structures in high-harmonic generation. We report detailed measurements of high-harmonic spectra in aligned nitrogen and carbon dioxide molecules. Varying the wavelength and intensity of the generating laser field, we show that the minimum in aligned N2 molecules is nearly unaffected, whereas the minimum in aligned CO2 molecules ...
متن کاملUncovering multiple orbitals influence in high harmonic generation from aligned
Recent measurements on high-order harmonic generation (HHG) from N2 aligned perpendicular to the driving laser polarization [B. K. McFarland el al, Science 322, 1232 (2008)] have shown a maximum at the rotational half-revival. This has been interpreted as the signature of the HHG contribution from the molecular orbital just below the highest occupied molecular orbital (HOMO). By using the recen...
متن کاملHigh harmonic generation from multiple orbitals in N2.
Molecular electronic states energetically below the highest occupied molecular orbital (HOMO) should contribute to laser-driven high harmonic generation (HHG), but this behavior has not been observed previously. Our measurements of the HHG spectrum of N2 molecules aligned perpendicular to the laser polarization showed a maximum at the rotational half-revival. This feature indicates the influenc...

متن کاملTheoretical exploration of the interference minimum in molecular high-order harmonic generation
The interference minimum in the molecular high-order harmonic generation is studied by numerically solving the non-Born-Oppenheimer approximation time-dependent Schrödinger equation. The results show that two kinds of interference minima appear in the high-order harmonic spectrum when the hydrogen molecular ion is exposed to the laser pulse. Furthermore, by adjusting wavelength of the laser as ...
