Description
Recent advances in laser technology and plasmonics, combined with knowledge from heavy-ion collisions, highlight the key role of resonating particles in boosting wave energy absorption, aiding fusion initiation.
In this study, we employ numerical modeling to investigate the interaction between laser radiation pulses and matter doped with gold nanoparticles of various shapes.
We investigate the response of gold-doped materials to short, intense bursts of infrared radiation, with a focus on the ejection dynamics of electrons from nanoantennas of different shapes.
Our analysis involves calculating and examining various properties, such as momentum and energy, of the resulting charges. Specifically, we compare the energies of ionization products under different doping scenarios to identify conditions that produce ions with the highest energy and momentum after a radiation pulse. Virtual experiments are conducted to investigate the effects of nanoantenna dopants with crossed and circular shapes, varying in size.
We track the dynamics of the interaction between the laser radiation and the doped matter, monitoring ionization products and their energies, as well as field intensities around resonating dopants.
These findings are pivotal for future fusion research, especially in the context of high energy short laser ignition pulses within the NAPLIFE project.
