Electro-Optical Radiation of a Charged Particle in a Single Laser Beam Field

TL;DR

This paper describes a unique electro-optical radiation phenomenon caused by a charged particle interacting with a laser beam, emphasizing phase synchronization and interference effects in a thin film medium.

Contribution

It introduces a novel mechanism of radiation arising from the interference of nonlinear oscillators excited by a monochromatic wave, with specific focus on phase synchronization effects.

Findings

Radiation is due to phase synchronization of oscillators by a wave field.

The effect is analyzed in a thin film with negligible density effects.

Long-wave part of the Weizsacker spectrum dominates the contribution.

Abstract

A peculiar radiation arising as a result of radiation interference of nonlinear oscillators excited by a monochromatic plane wave field of the incident particle is described. The radiation properties are determined by the fact that a phase of each oscillator radiation fields is synchronized by a wave field, while the radiation itself occurs due to the particle field influence on the oscillators. The consideration is performed for a thin film with negligible density effect. It is supposed that the contribution is given only by a long-wave part of the Weizsacker spectrum for which nonlinear polarization coefficients of medium are large.
