Abstract

We propose what we believe to be a novel method to reconstruct the spatiotemporal amplitude and phase of the electric field of ultrashort laser pulses using spatially resolved spectral interferometry. This method is based on a fiber-optic coupler interferometer that has certain advantages in comparison with standard interferometer systems, such as being alignment-free and selection of the reference beam at a single point. Our technique, which we refer to as the SpatioTemporal Amplitude-and-phase Reconstruction by Fourier-transform of Interference Spectra of High-complex-beams, offers compactness and simplicity. We report its application to the experimental characterization of chirped pulses and to spatiotemporal reconstructions of a convergent beam as well as plane-plane and spherical-plane waves interferences, which we check with our simulations.
