摘要
The focusing properties of Bessel-Gauss beams in the apertured case are studied on the basis of the generalized Huygens-Fresnel diffraction integral. Detailed numerical calculation results including the three-dimensional intensity distribution and isophotes (contours of equal intensity) have been given for different Fresnel numbers and truncation parameter of the system.
