6. PICOSECOND LABORATORY
(6-011, Prof. K.A. Nelson)

Mechanical and diffusive properties of materials are measured by 1) interferometric imaging, and 2) impulsive stimulated thermal scattering. Current projects include characterizing the glass transition in supercooled liquids, and determining elastic moduli in high-pressure energetic materials (collaboration with the Office of Naval Research).
