Complete spatial characterization of an optical wavefront using a variable-separation pinhole Pair

摘要

Characterizing the spatial and temporal properties of high harmonic generation (HHG) is crucial for understanding and controlling the dynamics of this extreme nonlinear process. Indeed, it has been shown that the macroscopic spatial properties of HHG encode details of the microscopic response of matter to an intense laser field: such as signatures of the interference of different quantum trajectories [1].
