Abstract

Three-dimensional (3D) analysis on the growth process of high-order harmonic generation (HHG) is achieved by integrating in situ measurement of a 3D phase-matching profile with interaction length control. Incorporating the phase-matching profile, calculation of high-order harmonic wave generation, and propagation reproduces the measured harmonics growth curve as well as distinctive features of the far-field beam profiles. The method resolves contributions of HHG from different positions of the driving beam affected by different sources of phase mismatch, and thus provides illuminating insight into the HHG process.
