Transient-grating single-shot supercontinuum spectral interferometry (TG-SSSI)
Abstract
We present a technique for the single-shot measurement of the spatiotemporal (1D s p a c e + t i m e ) 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.
