New Techniques for Investigating Properties of Energetic Solids at High Static and Dynamic Pressures.

摘要

A microscopic technique for determining the optical properties of solids at static high pressures is described. The applied pressure is measured by evaluating the shift in the sharp R-line of the fluorescence spectrum of a ruby crystal. Stress waves induced by a Q-switched ruby laser pulse are investigated, and the feasibility of using picosecond light pulses to generate far larger pressure gradients is examined. (Author)
