Abstract

We report an observation of large picosecond optical fluctuations of transmitted light when a coherent picosecond pulse propagates through a strongly disordered solid. These temporal fluctuations are a direct result of random interference among multitudinously scattered waves from different trajectories in the time domain. They appear without any dynamic motions of the medium, such as the Brownian motion of scatterers. A spatial average of the fluctuations yields a temporally smooth transmitted profile, while a time average of the fluctuations yields a spatially smooth scattering profile.
