Paper Abstract

We study multi-shot intensity-and-phase measurements of unstable trains of ultrashort pulses using two-dimensional spectral shearing interferometry (2DSI) [1] and self-referenced spectral interferometry (SRSI) [2] in order to identify warning signs of pulse-shape instability in these methods. 2DSI can signal instability with reduced fringe visibility, although this effect is very small when using small shears appropriate for large temporal support. SRSI can reliably indicate instability when two measured spectra are compared to an independent spectrum and a retrieved reference spectrum.
