Spatiotemporal field dynamics inside a nanowire laser ($l=7.5\mu \mathrm{m}$, $d=250\mathrm{nm}$). (a) and (d) Electric field intensity in an $xz$ and an $xy$ slice of the simulation volume during pumping. (b) ${\left|E\right|}^2$ averaged across transverse slices and plotted along $z$ and $t$. (e)–(g) Transverse intensity profiles inside the wire during lasing emission. (c) Intensity profile in an $xz$ slice after the maximum of the lasing emission.
