(a) Evolution of the spatial distribution of Ne along z-axis at position where energy deposition is higher for NP = 1 (for I = 1.4 × 1013 W/cm2), (dashed white line corresponds to the maximum depth for which OBT occurs while inset shows the temporal profile of Ne along the dashed line). (b) Top view of Parallel and (c) Perpendicular to laser polarisation LSFL for laser (peak) intensities I = 1.06 × 1013 W/cm2 and I = 1.4 × 1013 W/cm2, for NP = 3 and NP = 10, respectively. Black double-ended arrows indicate polarisation direction. (insets in (b,c) show the depth profiles along the dashed lines) (τp = 170 fs). Figures (b,c) illustrate a quadrant of the affected zone (top view) (λL = 2.6 μm).
