    Abstract

    Interferometric measurements of high harmonics induced by multiple laser fields represent a burgeoning field of research, offering prospects for optimized harmonic yield and enabling time- and space-resolved nonlinear spectroscopy. While most investigations have focused on controlling the time delay between pulses, our study introduces a novel approach. By manipulating an additional parameter—the phase difference between the fields—we unveil detailed insights into the physical mechanisms governing the ultrafast processes underlying high harmonic generation. Leveraging high harmonic 2-dimensional interferograms, our method facilitates the streamlined analysis of attosecond electron dynamics in complex molecules and solids, marking an important advancement in this rapidly evolving field.
