Tiivistelmä
We perform a detailed study of the spatial coherence of supercontinuum light generated in multimode fibers. We characterize the spatial coherence across the full spatial beam profile in both graded-index and step-index multimode fibers and observe a decrease of the coherence area with an increase of the injected pump power.
