Paper Abstract
The focusing properties and focal depth of amplitude modulation Gaussian beams are investigated. Numerical results
show that the intensity in the focus plane is circle shape in the low numerical-aperture optical system, while the intensity
distribution in the focal plane is ellipse shape in high numerical-aperture optical system due to contribution of
depolarized longitudinal component. Focal spot size and focal depth can be adjusted by changing geometrical parameters
and the modulation amplitude power n of Gaussian beams. The tunable range of the focal depth is very considerable.
