The on-axis intensity behavior of the diffracted Laguerre-Gaussian beam, LGp , by an opaque disk
In this work, we present a detailed study of the on-axis intensitydistribution of the Laguerre-Gaussian beam with no azimuthal index,diffracted by an opaque disk, by means of numerical simulation ofFresnel-Kirchhoff diffraction integral. We investigate the effect of theopaque disk size, the beam order, the beam waist, and the focal length.The results show that different focal phenomena may occur includingthe focal shift, focal split, and focal switch.
