Abstract
Processes underlying the formation of appreciably nonuniform structures in optical beams are examined using a hydrodynamics analogy. The influence of the focusing conditions on the characteristics of optical beams in vacuum is considered. Based on the geometric-optics approach, it is demonstrated that the axial distribution of radiation intensity for a focused beam is controlled by the initial transverse distribution of intensity and phase.
