Figure 3: Spatiotemporal dynamics in the non-linear propagation regime.
From: Sharply autofocused ring-Airy beams transforming into non-linear intense light bullets

Intensity isosurfaces for an EEGB (first row), an ECGB (second row) and a ring-Airy wavepacket (third row) at various positions along z after the non-linear focus. Beam propagation direction is from left to right.
