Experimental measurement of longitudinal component in the vicinity of focused radially polarized beam.
Experiments were carried out to study the focusing properties of radially polarized light. By direct recording of the focal pattern in photoresist, the intensity distribution in the vicinity of the beam focus was measured, and the non-propagating longitudinal component (z-component) was clearly demonstrated. Comparison with corresponding theory shows good agreement.
