Description
The recent revolution of lasers with increased power and shorter pulse length opens new possibilities for fusion energy research. The existence of detonations with time-like normal on space-time hyper-surfaces [1] combined with absorption adjustment using nanoantennas, allows for igniting the target in an opposing laser beam setup [2,3], avoiding instabilities. We describe both theoretical aspects and how the collaboration aims to investigate this novel idea experimentally by exploiting nano-technologies and knowledge from the field of high intensity plasmonics [4].
We summarize our latest achievements by briefly presenting theoretical comparative studies on possible energy deposition via optimized plasmonic nanoresonators [5], as well as results of kinetic studies analyzing the resilience of plasmonic nanoantennas [6]. We show results from experiments exploring the interaction between high-intensity femtosecond laser irradiation and UDMA-TEGDMA copolymer target doped with plasmonic gold nanorods. We present LIBS analysis of pure and doped mixture [7], along with intriguing morphological and structural changes during crater formation [8]. Additionally we analyze volume growth during crater formation to understand the impact of embedded plasmonic gold nanorods [9]. Finally, we present Raman spectroscopic study results on structural transformations in the copolymer upon irradiation [10].
