Transient Grating Single-shot Supercontinuum Spectral Interferometry (TG-SSSI)

Characterization of structured ultrashort laser pulses such as spatiotemporal optical vortices [1] , [2] demands a technique capable of capturing the spatiotemporal phase and amplitude of such pulses. Transient grating single-shot supercontinuum spectral interferometry (TG-SSSI) was developed to meet these demands and was successfully demonstrated in [2] . Here we present the details of TG-SSSI [3] and its possible extensions.
