Tight focusing of partially coherent and radiallly polarized vortex beams
Partially coherent and radially polarized vortex beam Large numerical aperture and diffractive optical element Spatial coherence Interesting beam patterns
2012/5/22
We investigate the tight focusing properties of partially coherent and radially polarized vortex beams by use of vectorial Debye theory. It is found that the intensity profiles and the degree of coher...
