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 YVO4 crystal used as a selector of radial polarization.

Schematic of experimental setups for the generation of a laser beam using a c-cut Ti:sapphire crystal. (a) Asymmetric confocal cavity with two high-reflectivity mirrors to demonstrate the laser oscillation and (b) modified laser cavity to improve mode matching between the laser and the pumping beams.
