FIG. 1.

Iso-surface plots of the laser intensities, where (a) shows the initial pulse as a reference, (b) shows the pulse after a propagating distance of with the input laser power (9.2 TW), and (c) shows the pulse after a propagating distance of with the input laser power (294 TW). Plasma electron density corresponding to the parameters in (c) is shown in (d).

FIG. 2.

Evolution of the laser peak intensity with the propagation distance. The left and right columns show 3D and 2D PIC results, respectively. Different rows correspond to different plasma densities. In each plot, the black dots correspond to the result in the vacuum and the other curves correspond to the cases in uniform plasmas for different initial laser powers. The initial laser spot radius is fixed as .

FIG. 3.

Evolution of the laser peak intensity with the propagation distance from 2D PIC simulations. The left and right columns correspond to the initial laser spot radius and , respectively. In each plot, the black dots correspond to the case in the vacuum and the other curves correspond to the cases in uniform plasmas for different initial laser powers.

Image of FIG. 4.
FIG. 4.

(a) Evolution of the laser peak intensity versus the propagation distance from 2D PIC simulation. (b) Spatial distributions of laser intensities normalized by the initial intensity at the time of . The plasma density has either uniform, channel, or anti-channel profiles, as shown in (c).
