Abstract
We implement a novel experimental technique for generating
mono- and polychromatic optical beams with on-axis single vortex by
manipulating polarization singularities of light in birefringent crystals.
We demonstrate that, in contrast to the well-known optical quadrupoles
generated by beams propagating along the optical axis of a uniaxial crystal,
the beam bearing isolated single-charge on-axis vortex can be generated if
the incident beam is tilted with respect to the optical axis at a certain angle.
