    • note
    • The interference effects will be significantly reduced if the sample roughness, or variation in thickness, approaches a significant fraction of the wavelength of the light. This accounts for the lack of interference observed in macroscopic shock interferometry experiments.

    • Previous observation of nearly linear (with some oscillations superimposed) time dependent phase data in nitrocellulose films provided initial support for the assumption of a constant particle velocity (Ref. 4).

    • note
    • Spot size and profile were measured with spatially resolved interferometry data at 200 ps. Use of higher energies than those employed here often led to self-focusing that caused a spike in the center of the Gaussian profile. No data influenced by self focusing were reported here.

    • note
    • The spectrally clipped pulse is slightly chirped from ∼155 fs to 200 fs to expand the spatial region of overlap between the sample and reference pulses in the interferometer. This is required to achieve sufficient fringe contrast over the entire shocked region at the magnification employed.

    • Caution is advised against untested extension of the agreement between thin film and bulk Hugoniots to nonglassy materials, where structural properties (such as crystal defects or grain boundaries) may occur on length scales larger than the film thickness.
