00925njm 22002777a 4500 dc Piquero Sanz, Gemma María author Mejías López, Jesús Ángel author Martínez Herrero, María Rosario author Movilla Serrano, Jesús María author 2002 We present an approach for describing the spatial structure of partially polarized light fields. Unlike the treatments usually encountered in the literature, in which the polarization state is represented by position-dependent functions, the formalism shown here characterizes the polarization by means of a family of measurable overall parameters averaged over the transverse spatial region where the beam intensity reaches significant values. Generalized degrees of polarization are introduced to evaluate the uniformity of the spatial distribution of the polarization state of the beam-like field. The possibility of improvement and optimization of the quality of a polarized laser beam (understood as the general usefulness of such field for collimation and focussing) is analyzed by employing first-order optical systems. Finally, attention is briefly devoted to non-paraxial electromagnetic vector beams, whose Parametric description of their polarization properties constitutes, at present, a challenge for theoreticians.
