Abstract

This chapter explains the manufacture and assembly of gas-gun investigations of bulk material properties and reactions required for accuracy of results. The measurement of targets in recording, calibrating, evaluating pin and optical probe data is discussed for their importance and usage in experiments involving laser generated shocks. The chapter describes the methods of obtaining reproducible and meaningful data by optimizing the laser pulse shape to produce supported shocks. The role of optical effects, such as shock induced changes in material complex conductivity and thin film interference are covered in the chapter. An interferometric tool termed as the ultrafast dynamic ellipsometry, which is capable of measuring small changes in complex conductivity that might result from melt or a phase transition, as well as the shock and particle velocities, and index of refraction, in shocked transparent dielectric materials is explained. The chapter has references to further resources at the end.
