Figure 7: NLSE-simulated 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 from NLSE simulations for the same four pump energies and same five propagation times as shown in Fig. 6a. The colour bar indicates the dimensionless refractive index change. (b) Spectra of the transmitted pump pulses from NLSE simulations, for direct comparison with measured spectra shown in Fig. 6b. (c) Solid curves: NLSE-simulated pump transverse spatial profiles at 
=0 near the exit plane (tob=12.2 ps, zob=2.5 mm) for pump energy from 0.4 to 0.6 μJ, and at tob=7.4 ps (zob=1.5 mm) for 0.7 μJ. Dashed curves: corresponding lineouts of FDT-reconstructed pump spatial profile from Fig. 6a for direct comparison.
