Abstract: (1193 Views)
In this paper propagation of a Lorentz-Gauss beam passing through a circular aperture and a lens is discussed by using Collins integral. With the aid of axial intensity, the Focal Shift and effect of aperture-lens separation and radius of aperture have been studied. The results show that Focal Shift decreases with the increasing values of radius of aperture.
