“…It can be created by ionizing a gas [14] or a porous medium, e.g., a foam with a low-volume density placed in front of the plastic ablator by a low-energy prepulse [15,16]. A near-critical-density (NCD) preheated foam plasma can also be produced by X-ray radiation from a nearby laser-plasma source [17,18], or by using a thin (<1000 Å) layer of a high-Z material, which is deposited on the target surface or incorporated into the foam facing the laser [19][20][21]. In the latter case, laser-heated high-Z plasma effectively re-radiates in the soft X-ray range, causing uniform ablation of the target.…”

The hydrodynamics of plasma formed in the interaction of 100 ns UV KrF laser pulses with foam targets with volume densities from 5 to 500 mg/cm3 was studied. Initial and dynamic transmittance at 248 nm wavelength were measured. At intensities of about 1012 W/cm2, the propagation rates of radiation through foam targets reached 80 km/s, while plasma stream velocities from both the front and rear sides of targets were approximately the same, ~ 75 km/s, which confirms a volumetric absorption of radiation within the target thickness and the explosive nature of the plasma formation and expansion.
