FIG. 1.

Elastic longitudinal stress-particle velocity Hugoniot for single-crystal sapphire. Experimental data are reproduced from Refs. 1 and 11–13. Our best-fit linear function [Eq. (1)] was generated using all available points in the elastic range.

FIG. 2.

Summary of (a) shock velocity-particle velocity and (b) longitudinal stress-particle velocity Hugoniot for single-crystal sapphire in the inelastic range of compression. Experimental data are reproduced from Refs. 11–13 and 20. The best-fit curve [Eq. (3)] was generated using all available points in the inelastic range.

FIG. 3.

Typical spectral dependence of light transmission through shocked sapphire (data from experiment 8). Each spectrum represents a interval during the experiment. Smooth noise-free segments spanning the 470–520-and ranges indicate the “dark” masked-off regions of the streak camera photocathode. The actual transmittance data in these dark regions were restored by interpolation between the adjacent “bright” areas. No wavelength dependence upon the loss of transmission was typical of all other experiments as well.
