Abstract

Femtosecond reflectivity measurements on Fe and Al targets provide evidence for the vacuum heating absorption mechanism. The effect occurs for obliquely incident laser pulses polarized in the plane of incidence at intensities above 1014 W/cm2. The electron oscillation normal to the surface leads to this widely predicted absorption effect, whose first experimental observation is reported in the current work.
