Control of recollision wave packets for molecular orbital tomography using short laser pulses
Abstract. The tomographic imaging of arbitrary molecular orbitals via high-order harmonic generation requires that electrons recollide from one direction only. Within a semi-classical model, we show that extremely short phase-stabilized laser pulses offer control over the momentum distribution of the returning electrons. By adjusting the carrier-envelope phase, recollisions can be forced to occ...
متن کاملRole of molecular orbital symmetry on the alignment dependence of high-order harmonic generation with molecules
It is shown that the alignment dependence of the yields of high-order harmonic generation sHHGd from molecules by intense lasers is governed by the orbital symmetry of the outermost electronssd. For N2, with its outermost sg electron, the HHG yield is maximal when the molecules are aligned with the laser polarization direction, in agreement with the recent experiment of Itatani et al. fNature 4...
متن کاملMapping molecular orbital symmetry on high-order harmonic generation spectrum using two-color laser fields.
We have measured high-order harmonic generation spectra of D2, N2, and CO2 by mixing orthogonally polarized 800 and 400 nm laser fields. The intensity of the high-harmonic spectrum is modulated as we change the relative phase of the two pulses. For randomly orientated molecules, the phase of the intensity modulation depends on the symmetry of the molecular orbitals from which the high harmonics...
متن کاملMolecular orbital tomography from multi-channel harmonic emission in N2
High-order harmonic generation in aligned molecules can be used as an ultrafast probe of molecular structure and dynamics. By characterizing the emitted signal, one can retrieve information about electronic and nuclear dynamics occurring in the molecule at the attosecond timescale. In this paper, we discuss the theoretical and experimental aspects of molecular orbital tomography in N2 and inves...
متن کاملDiffractive molecular orbital tomography
High harmonic generation in the interaction of femtosecond lasers with atoms and molecules opens the path to molecular orbital tomography and to probe the electronic dynamics with attosecondÅngström resolutions. Molecular orbital tomography requires both the amplitude and phase of the high harmonics. Yet the measurement of phases requires sophisticated techniques and represents formidable chall...
