Abstract

We propose a novel approach employing structured sampling and a single-pixel detector to measure, simultaneously, the spatial profile and the spatially resolved temporal profile of a femtosecond laser beam with an autocorrelation method. The experimental system integrates a Digital Mirror Device (DMD) into a conventional autocorrelation setup. An experimental comparison with a raster scanning method illustrates the advantages of this setup, achieving comparable accuracy with reduced energy levels. This study introduces a promising technique for the precise characterization of ultrafast laser pulses, with potential applications in various fields that demand accurate spatial and temporal measurements as material processing or imaging applications.
