Abstract
Vortex beams have been widely analyzed and applied in various fields owing to their unique phase and intensity distribution, along with their orbital angular momentum; they can be produced through various methods. This study proposes a method based on polarization holography, contrary to the traditional method of producing vortex beams. This method is significant in that the signal wave in the recording stage is not the generated vortex beam; the reconstructed wave is the vortex beam obtained in the reconstruction stage, which varies from the vortex beams produced by holography, where the signal wave is already a vortex beam. Faithful reconstruction of polarization holography is applied in the experiment, where phenanthrenequinone-doped polymethyl methacrylate (PQ/PMMA) photopolymers are used as the recording material. Scalar vortex beams with arbitrary linear polarization and topological charges can be produced by changing the experimental parameters. The experimental results are satisfactory. Additionally, this work demonstrates the application of polarization holography in light field manipulation. This proposed method has potential applications in optical micro-manipulation and optical tweezers.
