Abstract Scope |
Lasers can produce extreme pressures, ideal for material testing and processing. Tampers are optically transparent media placed on the laser-incident side of targets in direct drive experiments to enhance pressure generation. Materials must be optically transparent to the laser wavelength for photon transmission to the target while enduring rapid energy deposition long enough to enable momentum transfer. By inhibiting surface expansion and energy loss from phase transformations, tampers increase pressure coupling at the target interface. Various ceramic, non-crystalline, and other well-ordered materials are chosen in these applications for their unique material properties to maximize the amount of front-side pressure. Previous work utilizes facility-scale, high through-put lasers, with ongoing efforts on both large and small platforms. This work aims to correlate material properties like acoustic velocity, density, crystal structure, Modulus, refractive index etc. to experimental performance in various tampers such as Sapphire, Fused Silica, Lithium Fluoride, YAG, and GGG. |
