The coherent artifact in interferometric pulse-measurement techniques

by Rhodes, Michelle; Mukhopadhyay, Madhuri; Birge, Jonathan; Steinmeyer, Gunter; Rahaman, Saidur; Trebino, Rick

We study multi-shot intensity-and-phase measurements of unstable trains of ultrashort pulses using two-dimensional spectral shearing interferometry (2DSI) and self-referenced spectral interferometry (SRSI) in order to identify warning signs of pulse-shape instability.
