Abstract: | Tight focusing properties of azimuthally polarized Lorentz Gaussian vortex beam through a dielectric interface are numerically studiedby vector diffraction theory. The focusing properties,such as spot size, depth of focus,and maximum intensity position,are numerically calculatedby properly manipulating the Lorentz parameter with/without annular obstruction values. Thus,using annular obstruction,one can generate a highly confined focal spot of long focal depth when using an azimuthally polarized Lorentz Gaussian vortex beam. |
