Plasmonic metamaterials for high delta-V laser ablation propulsion in cislunar orbits
Abstract
The objective of this proposal is to examine nanosecond pulsed laser ablation of nanostructured metallic targets for controlling and enhancing ablation processes by means of advancing laser ablation propulsion by exploiting plasmonic effects in nanostructured ablation targets. For this purpose PI proposes to examine high-fluence nanoscecond laser beam interaction with nanostructured metallic surfaces, for high efficiency ablation propulsion leading to high specific impulse. Proposal seeks to advance current state of the art where femtosecond laser ablation is insufficient to creating high specific impulse systems that are needed for future cislunar operation.
