FIG. 1.

(a) Schematic of the target consisting of a -thick plastic (CH) foil followed by a -thick layer of foam with a density of . (b) On-target laser intensity as a function of time for two pulse shapes, with a picket used in the DS method of adiabat shaping (dashed line) and without a picket (solid line).

FIG. 2.

Optical-depth radiographs of the targets driven without a picket (upper three images) and with a picket (lower three images), showing the growth of imprinted features at 120-, 60-, and wavelengths. All radiographs were taken when the target had traveled .

Image of FIG. 3.
FIG. 3.

Optical-depth modulations as a function of time for foam targets irradiated with sinusoidal intensity perturbations of wavelengths of (a) , (b) , and (c) . Data with no picket are plotted as diamonds and data with a picket are plotted as triangles.

Image of FIG. 4.
FIG. 4.

Measured imprint efficiency as a function of spatial wavelength. Data with no picket are plotted as diamonds, connected by a solid line, and data with a picket used in the DS method of adiabat shaping are plotted as triangles connected by a dashed line.

Image of FIG. 5.
FIG. 5.

On-target laser intensity as a function of time for two pulse shapes—with a picket used in the RX method of adiabat shaping (dashed line) and without a picket (solid line).

Image of FIG. 6.
FIG. 6.

Measured imprint efficiency as a function of spatial wavelength. Data with no picket are plotted as diamonds, connected by a solid line, and data with a picket used in the RX method of adiabat shaping are plotted as triangles connected by a dashed line.
