    Vortex radii of perfect vortex beams are independent of the topological charge and carry orbital angular momentum, and these beams have wide applications in optical communications, quantum optics, and laser manufacturing. In this study, radial phase-shifted spiral zone plates that can generate perfect vortex beams have been fabricated using two-photon photopolymerization direct laser writing. The vortex radii of perfect vortex beams are adjusted by changing the control parameter of the radial phase-shift. Moreover, interference patterns verify that the orbital angular momentum carried by vortex beams is consistent with the designed topological charge. Thus, this study can provide a reference for the rapid design and manufacture of photonic chip integration.
