Interferometric data resolved to 1 {μ}m and 15 psec confirm the significant role of radiation pressure during high-intensity laser-plasma interactions. Specifically observed manifestations include electron density profiles steepened to {~}1-{μ}m scale length, clearly defined upper and lower density shelves, and small- and large-scale deformations of transverse isodensity of surfaces.
