Overcoming the Child Langmuir law via Pondermotive Potential of the intense lasers

TL;DR

This paper proposes a method using the ponderomotive potential of intense lasers to surpass the Child-Langmuir current limit in vacuum tubes, potentially increasing the maximum current by over 200%.

Contribution

It introduces a novel scheme leveraging laser-induced ponderomotive potential to exceed traditional vacuum current limits.

Findings

Maximum current can be increased by a couple of hundred percent.

The proposed scheme effectively overcomes the Child-Langmuir law limit.

Theoretical estimation supports significant enhancement of vacuum tube current.

Abstract

The maximum current that could be carried in a vacuum tube is given by the so-called Child Langmuir law. A scheme where this limit could be overcome via the pondermotive potential is proposed. The estimation shows that the limit could be overcome by a couple of hundred percents.
