Nanoplasmonic Laser Fusion. Response to F\"oldes and Pokol -- Letter to the Editor

TL;DR

This paper defends nanoplasmonic laser fusion by proposing a novel approach that combines space-time hyper-surface detonations with nanoantenna-regulated laser absorption, enabling volume ignition in a simple in-line setup.

Contribution

It introduces a new method for laser fusion that utilizes hyper-surface detonations and nanoantennas to achieve volume ignition with a straightforward two-beam configuration.

Findings

Refutes previous criticisms of nanoplasmonic laser fusion.

Proposes a practical in-line laser fusion setup using nanoantennas.

Demonstrates potential for volume ignition in fusion targets.

Abstract

F\"oldes and Pokol in their letter "Inertial fusion without compression does not work either with or without nanoplasmonics" criticized our works \cite{CS2015,CKP2018}. Here we refute their argumentation. Our proposed improvement is the combination of two basic research discoveries: (i) The possibility of detonations on space-time hyper-surfaces with time-like normal (i.e. simultaneous detonation in a whole volume) and (ii) to increase the ignition volume to the whole target, by regulating the laser light absorption using nanoantennas. These principles can be realized in an in-line, one dimensional configuration, in the simplest way with two opposing laser beams as in particle colliders \cite{CsEA2020,Bonasera2019}.
