Abstract:
"Diffraction-free" (Besselian) light beams are formed by conic optical elements (lenses, mirrors)-axicons. This type of beam essentially differs from the Gaussian one by constant diameter of its axial caustic, by axisymmetrical side power input to the caustic zone at a fixed angle, and by a Besselian intensity distribution over the beam cross-section. Theoretical and experimental data on the Besselian beam structure are compared; three regimes of optical breakdown for such beams are considered.
