Direct observation of quantum-path interferences in high order harmonic generation
The European Physical Journal - Special Topics Springer Berlin / Heidelberg 175 (2009) 191-194-191-194
Abstract:
Intensity dependent high harmonic generation was investigated when both short and long trajectories contribute to the emission. We have directly observed for the first time clear indication of quantum-path interference through harmonic spectrum modulations.High precision self-referenced phase retrieval of complex pulses with multiple-shearing spectral interferometry

Ionization effects on spectral signatures of quantum-path interference in high-harmonic generation
Opt. Express OSA 17 (2009) 7
Abstract:
The interference between the emission originating from the short and long electron quantum paths is intrinsic to the high harmonic generation process. We investigate the universal properties of these quantum-path interferences in various generation media and discuss how ionization effects influence the observed interference structures. Our comparison of quantum-path interferences observed in xenon, argon, and neon demonstrates that our experimental tools are generally applicable and should also allow investigating more complex systems such as molecules or clusters.Measuring measurement: theory and practice
