文摘The precise spatiotemporal characterization of broadband ultrafast laser beams is essential for accurate laser control and holds significant potential in photochemistry and high-intensity laser physics.Existing methods for spatiotemporal characterization,such as frequency-resolved optical gating(FROG)and compressed ultrafast photography(CUP),are often spatially averaged or suffer from limited spatial resolution.
