Extended Data Fig. 6: Measurements of temporal coherence of a laser beam using Michelson interferometry.

The fringe visibility as a function of the time delay between the two interferometer arms (blue points) is fitted to the biexponential decay (red line). The time constant of the longer-lived component is ~700 fs. The inset shows a representative interferogram.
