We discussed the radial intensity distribution in the presence of spherical aberrations (SA) for cases in which the incident field is a focused Gaussian spot. A numerical solution of a two dimensional integral diffraction (paraxial ray) equation for a relatively large SA is developed by using the we

The phase singularities of focused dark-hollow Gaussian beams in the presence of spherical aberration are studied. It is shown that the evolution behavior of phase singularities of focused dark-hollow Gaussian beams in the focal region depends not only on the truncation parameter and beam order, but
