title: Generation of radially polarized Ti:sapphire laser beam using a c-cut crystal.
abstract: First, it is demonstrated that with a c-cut Ti:sapphire crystal the generation of a nonpolarized laser beam is possible, in contrast to the conventional a-cut Ti:sapphire crystal, which produces a linearly polarized beam. Second, the generation of a radially polarized Ti:sapphire laser beam is demonstrated in combination with a c-cut YVO(4) crystal used as a selector of radial polarization.
