Abstract

We generate high order harmonics in aligned CO₂ molecules and measure the spectral amplitudes and phases as a function of the alignment angle. We control the quantum interference occurring in the recombination of an ultrafast laser-driven electron wavepacket with the highest occupied molecular orbital of CO₂. By comparing to the emission of the reference system krypton, we obtain an experimental measure of the complex recombination dipole matrix element between the CO₂ HOMO and a continuum state. The measured phase jump contains signatures of Coulombic wavepacket distortion.
