The effects of different apertured modulations on propagation features
of the first-order Bessel beam. The effects of different apertured mo
dulations on the propagation characteristics of the first-order Bessel
beam are numerically investigated. The calculated results demonstrate
that the variations of the first peak intensity of the J(1) Bessel be
am with propagation distance are similar to the axial intensity distri
butions of the apertured J(0) Bessel beam. These results may offer use
ful information for improving the quality of the J(1) Bessel beam in p
ractical applications.
