Abstract
The formation of the spatial intensity profile of a laser beam in a system consisting of a square serrated aperture stop and a spatial filter has been studied. This paper discusses how various shapes of the serrations of the stop, as well as various radiation-selection angles in the spatial filter, affect the resulting beam profile. The far fields of the beams formed by the serrated stops are analyzed. Special attention is paid to the question of maintaining the spatial structure of apodized beams when they freely propagate in space.
