\(B_z\) distributions at different slices along the z-direction (\(z=0, \pm 5 \lambda _L, and \pm 10 \lambda _L\)) at (a) \(\mathrm {t=250~fs}\) and (b) \(\mathrm {t=300~fs}\). (c) Distribution of \(B_z\) in the \(y-z\) plane at \(\mathrm {t=300~fs}\). (d) Time evolutions of \(B_z\) at \(z=0, \pm 4 \lambda _L, \pm 8 \lambda _L, and \pm 10 \lambda _L\) along the central line.
