The technique presented in this study allows for the single-shot measurement of the spatiotemporal amplitude and phase of ultrashort laser pulses. It is suitable for characterizing short pulses carrying optical vortices and pulses containing singularities associated with spin/orbital angular momentum or polarization.
We present a technique for the single-shot measurement of the spatiotemporal (1D space + time) amplitude and phase of an ultrashort laser pulse. The method, transient grating single-shot supercontinuum spectral interferometry (TG-SSSI), is demonstrated by the space-time imaging of short pulses carrying spatiotemporal optical vortices. TG-SSSI is well suited for characterizing ultrashort laser pulses that contain singularities associated with spin/orbital angular momentum or polarization. (C) 2021 Optical Society of America
