Abstract

We demonstrate that the trajectory of a point-charge in a radially polarized laser Bessel beam may be stable similar to the case of a positron that bounces back and forth in the potential well generated by two adjacent atomic planes.

Summary

The stable trajectory of a charged particle in an external guiding field is an essential condition for its acceleration or for forcing it to generate radiation. Examples of possible guiding devices include a solonoidal magnetic field or permanent periodic magnet in klystrons, a wiggler in free-electron lasers, the lattice of any accelerator, and finally the crystal lattice for the case of channeling radiation.
We demonstrate that the trajectory of a point-charge in a radially polarized laser Bessel beam may be stable similar to the case of a positron that bounces back and forth in the potential well generated by two adjacent atomic planes. While in the case of channeling radiation, the transverse motion is controlled by a harmonic oscillator equation, for a Bessel beam, the transverse motion is controlled by the Mathieu equation. The characteristics of the motion are presented.
