Abstract

Ultrafast pulsed lasers are integral for a variety of industrial, medical, and scientific endeavors. Fundamentally, pulsed lasers are complicated four-dimensional space-time phenomena that can be described by their complex spatiotemporal electric field profiles. Here we present the first ever single-shot, full-field, reference-free spatiotemporal pulse-beam measurement system capable of single-pulse characterization. Our technique combines single-shot spatiospectral characterization from broadband single-shot ptychography (BBSSP) with a collocated single-shot spectral phase measurement from single-shot frequency resolved optical gating (SSFROG). Together, these measurements provide the full complex spatiospectral field at the plane, which can be computationally propagated and Fourier transformed to provide the spatiotemporal profile of the pulse at any plane.
