Résumé

The influence of foams on laser shocks was studied with ns laser pulses smoothed with phase zone plates and focused onto layered foam-aluminum targets. Foams of 5-200 mg/cm³ density and 60 μm thickness were used. A strong pressure increase was measured with the foam in comparison to focusing the beam directly onto aluminum due to impedance mismatch at the aluminum-foam interface. Below a particular density, the measured pressure decreased as a result of hydrodynamics effects. Results are compared with computer simulations.
