Paper Abstract

We show that when a partially coherent beam with a Gaussian intensity distribution is focused by a lens, the intensity distribution near geometrical focus is strongly dependent upon the spatial coherence. Based on this, the desired intensity distribution near the focus can be generated by choosing appropriate form of spatial coherence. It is shown that the partially coherent flat-top intensity distribution near the geometrical focus or a partially coherent bottle beam can be produced by choosing appropriate forms of spectral degree of coherence. The influence of some parameters of the incident beams on the resultant beams near geometrical focus is investigated.
