Figure 6: Single-shot tomographic movies of the evolving index profile.
From: Single-shot tomographic movies of evolving light-velocity objects
(a) Selected 2D snapshots Δn(
, xob) of the pump nonlinear index profile at five different propagation times tob indicated at the top and pump energies indicated at left. The horizontal axis of each snapshot is given in local position 
. The colour bar shows the dimensionless refractive index change. (b) Spectra of the transmitted pump pulses. The spectrum in the top row is nearly identical to the incident spectrum. (c) Near-field images of the transmitted pump spatial profiles, with a resolution of ~20 μm. Scale bar, 30 μm.
