|Abstract:||We convert a linearly polarized Gaussian beam into a radially polarized doughnut beam with an eight-segment spirally varying retarder (SVR) at wavelength of 808 nm. The SVR is designed based on the linear birefringence of α-barium borate (α-BBO) crystal and fabricated using a dry etching process. Radially polarized light of high purity (> 96% at farfield distribution) was generated experimentally using the segmented SVR positioned between two quarter waveplates with orthogonal slow axes. The emergent polarization can be switched between radially and azimuthally polarized cylindrical vector beams with a pair of half-wave plates. © 2008 Optical Society of America.|
