摘要：

A new method is proposed of Bessel beam generation by means of generation of a special mode of electromagnetic field in a confocal resonator with annular active medium. An estimation of the size of the "diffraction-free" zone are presented. A proposal is made to apply a Bessel beam to accelerate a beam of charged particles. © 1990.
