Laser resonator configurations for obtaining pure azimuthal and radial polarized beams are presented. They involve the coherent summation, inside the laser resonator, of two orthogonally polarized TEM[sub 01] modes. Basic principles and experimental results with a Nd:YAG laser are presented. The results include a full space variant polarization measurement and show efficient formation of high-quality azimuthal and radial polarized beams. © 2000 American Institute of Physics.

    The interference of polarized beams in thin CdS crystals placed between crossed polarizers is considered. It is shown that in the case of incomplete polarization of the interfering beams the spectral position of the transmission minimum near the isotropic point depends on the crystal thickness.

    It is shown how one can choose suitable combinations of Siberian Snakes and betatron phase advances to optimize the ability of a ring to accelerate a polarized beam with little reduction of polarization. In an analysis of HERA-p, these methods have lead to a 14-fold increase of the vertical beam...
