Paper Abstract

The space-time dynamics of a pulsed Bessel beam envelope behind the axicon is studied in detail theoretically and experimentally. It has been discovered and explained the phenomenon of appearance of an additional pulsed beam (satellite) behind the axicon. The dependence of the axial intensity of the output diverging femtosecond Bessel beams on the distance from the axicon has been calculated and measured. It is established that the Bessel pulsed beam diameter increases, the axial intensity slowly decreases with increasing the longitudinal coordinate, and the zone of existing the pulsed Bessel beam is very long. It is shown that in schemes with the diverging and converging initial Gaussian pulse differing in the lens position, one can generate femtosecond Bessel beam with the required parameters (zero-maximum diameter and intensity) using only a single axicon and a lens.
