متن کاملManifestation of the Gouy phase in strongly focused, radially polarized beams.dvi
The Gouy phase, sometimes called the focal phase anomaly, is the curious effect that in the vicinity of its focus a diffracted field, compared to a non-diffracted, converging spherical wave of the same frequency, undergoes a rapid phase change by an amount of π . We theoretically investigate the phase behavior and the polarization ellipse of a strongly focused, radially polarized beam. We find ...

متن کاملBeam width of highly-focused radially-polarized fields.
On the basis of a formal analogy with the irradiance moments, analytical definitions are proposed for the width of both the transverse and the longitudinal component of rotationally-symmetric radially-polarized fields at the focal plane of a high-focusing optical system. The beam width of the whole field is also introduced. The transverse beam size is thus associated with the overall spatial st...
متن کاملFields of a tightly focused radially polarized laser beam: the truncated series versus the complex-source-point spherical wave representation
In this paper, the fields of a radially polarized fundamental Gaussian beam are derived with a complex-source-point spherical wave approach and then compared and contrasted with those derived recently from a Lax series to the order of ε15, where ε is the diffraction angle. It is shown that the domain of validity of the derived fields is restricted by a discontinuity built into the vector potent...
