Uncovering 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 کاملOrigin and implication of ellipticity in high-order harmonic generation from aligned molecules
We address theoretically and numerically the possibility of observing ellipticity in high-order harmonic generation (HHG) from aligned molecules driven by linearly polarized fields—a subject of controversy in the recent literature with significant implications. To that end we develop a numerical method for solution of the electronic dynamics and extend a recently developed theory of HHG from al...
متن کاملRevival Structure of High-order Harmonic Generation Signals from Adiabatic and Switched-off Aligned Molecules
It is believed so far that the high harmonic generation (HHG) signal of adiabatically aligned molecules does not show any revival structure. This paper demonstrates the existence of revival structure of HHG signals of molecular ensemble aligned by using adiabatic as well as switched-off schema. The results are presented in the externally available control parameters – the delay-time, d t , betw...
متن کاملProbing molecular frame photoelectron angular distributions via high-order harmonic generation from aligned molecules
We analyse the theory of single photoionization (PI) and high-order harmonic generation (HHG) by intense lasers from aligned molecules. We show that molecular-frame photoelectron angular distributions can be extracted from these measurements. We also show that, under favourable conditions, the phase of PI transition dipole matrix elements can be extracted from the HHG spectra. Furthermore, by v...
