Paper Abstract

Interactions of PALS iodine laser beam with low density porous targets and porous targets with Al foil attached to the rear side were studied using multi-frame interferometry and shadowgraphy. Electron density profiles at the front and the rear side of the targets were reconstructed from interferograms. Velocities of Al-foils accelerated by the pressure of the heated porous material were established from shadowgrams. A good symmetry and absence of local perturbations were observed both in the rear side plasmas of porous targets and in the shape of the accelerated Al-foils. Measured rear side velocities are in a good agreement with the presented theory of laser interactions with porous materials.
