RT Journal Article T1 Generation and characterization of spirally polarized fields A1 Piquero Sanz, Gemma María A1 Ramírez Sánchez, Victoria A1 Santarsiero, Massimo AB Recently introduced global parameters for describing the polarization of a beam are used to characterize spirally polarized fields, which include as particular cases azimuthally and radially polarized fields. Theoretical predictions about such global parameters are experimentally confirmed by generating beams with spirally polarized transverse patterns, by means of two different procedures.
