Image of FIG. 1.
FIG. 1.

Spatial distribution of the charge density and the cycle-averaged electrostatic space-charge field along the laser propagation direction at . The simulation parameters are , , , , and . The highly compressed electron and ion layers and the ultraintense space-charge electric field associated with the collisionless shock, as well as the development of lateral striation in the charge density, can be observed.

FIG. 2.

Ion density distribution (top) and phase space distribution (bottom) at (left), (center), and (right). The simulation parameters are the same as for Fig. 1.

Image of FIG. 3.
FIG. 3.

Spatial distributions of charge density at . The simulation parameters are the same as for Fig. 1.

Image of FIG. 4.
FIG. 4.

Spatial distributions of the ion density (top) and the phase space distribution (bottom) at (left) and (right). The simulation parameters are the same as for Fig. 1, except that the target thickness is .

Image of FIG. 5.
FIG. 5.

Time evolution of the ion density and energy density at behind the rear target surface on the laser propagation axis. The simulations parameters are the same as for Fig. 1, except (red, solid) and (black, dashed).

Image of FIG. 6.
FIG. 6.

Time evolution of the peak ion energy in the interaction of a CP laser pulse (, ) with solid targets of different thickness: (filled circles), (filled squares), (open circles), (filled stars), (open triangles), (filled triangles). Note that the thickest target does not correspond to the highest ion energy.

Image of FIG. 7.
FIG. 7.

Spatial distribution of the ion density at (a) and (b) for laser pulse with sharp-rising (instead of Gaussian) front profile. The black curves in (c) and (d) show the corresponding variation of along . The simulation parameters are , , , and .
