Generation of radially polarized beams and higher order polarization singularities by optical parametric amplification of optical vortices

We show a method to form radially and azimuthally polarized beams as well as higher order polarization singularities by superposition of optical vortices with opposite topological charges obtained by optical parametric amplification. The proposed method could find applications in optical trapping of...

Description
Summary:We show a method to form radially and azimuthally polarized beams as well as higher order polarization singularities by superposition of optical vortices with opposite topological charges obtained by optical parametric amplification. The proposed method could find applications in optical trapping of particles, nonlinear optics experiments, and laser material processing.
