Abstract: Layers of low density porous materials offer various applications in laser plasma interaction experiments. Two experimental studies of laser-foam interaction are presented. Firstly, time-integrated and time-resolved transmission of the laser beam through a layer of underdense plastic TAC (C 12 H 16 O 8 ) foam was measured. The data are required for the design of dynamic smoothing of inhomogeneities inside a laser beam by its propagation through an underdense foam. Secondly, emission of K-shell lines from TMPTA (C 15 H 20 O 6 ) foams of density 10 and 20 mg/cc doped by 10 or 20 weight % of chlorine was measured with a high spectral (>5000) and spatial (<10 μm) resolution. The demonstrated formation of a relatively thick homogenous plasma layer close to the foam surface may be used for atomic physics studies of multiply ionized dense plasmas.
