The aim of this paper is to explore high-fidelity phase-front transfer for optical vortices via four-wave mixing. Based on a dual-pump non-degenerate four-wave mixing configuration, an optical vortex is encoded in the phase of an arbitrary input beam. We investigate the phase profile of the generated beam and its dependency on the system parameters. Using first-order perturbation theory, we solve the density matrix elements related to the atomic medium polarization, establish the coupled-wave equations for the propagation of the generated probe and conjugate beams within the medium, and obtain analytical expressions for the Rabi frequencies of the two optical fields. The coherent transfer of optical vortices among beams is simulated. Furthermore, the research highlights the impact of frequency detuning and dephasing rate on the vortex phase distribution. The results indicate that frequency detuning not only affects the strength of light-atom interaction and the efficiency of four-wave mixing but also modulates the vortex wavefront of the generated beams, leading to phase distortion. Reducing the dephasing rate of the system ensures that high-fidelity coherent mode transfer of the optical vortex can be achieved even under single-photon detuning. Conversely, when the system coherence is better preserved, two-photon detuning induces more pronounced phase distortion in the vortex beam. Therefore, to achieve high-fidelity optical vortex transfer, it is necessary to minimize both the dephasing rate and the two-photon detuning. These findings provide an optimized scheme and theoretical foundation for the experimental realization of high-fidelity optical vortex transfer, offering significant reference value in the application field of vortex four-wave mixing, such as high-dimensional quantum communication and information processing based on orbital angular momentum.
