Abstract An interferometric method is used in the picosecond range to study the evolution of shock-compression waves generated in metallic film specimens by a powerful femtosecond laser. Shock waves with compression stress behind the elastic precursor front up to 27.5 GPa and 12.6 GPa, respectively, were registered in the case of submicron propagation length in iron and aluminum. The obtained values of the shear and bulk strength are comparable with computed values of the theoretical ultimate shear and tensile strength.
