Torque-operated gradient-index axicon

We describe a gradient-index axicon based on twisting of crystals. We demonstrate that the focal length of the axicon can be efficiently operated by the torsion moment.

Description
Summary:We describe a gradient-index axicon based on twisting of crystals. We demonstrate that the focal length of the axicon can be efficiently operated by the torsion moment. The working analytical relations describing the focal length of the axicon and its dependence on different geometrical parameters as well as the torsion moment has been derived.
