Abstract
The polarisation-dependent effect of the astigmatic transformation of vortex beams focused perpendicular to the axis of a uniaxial crystal is investigated theoretically and experimentally. The dependence of the transformation on the polarisation state of a beam incident on a crystal was studied numerically in detail, showing the influence of the polarisation state on the individual electric field components of ordinary and extraordinary beams. The experimental results are in agreement with theoretical studies. The results obtained can be used for the generation and detection of optical vortex beams in optical communication systems and in the field of polarisation-controllable optical manipulation of nano- and microparticles.
