摘　　要：We propose a scheme for generating high-quality single-photon sources utilizing the conventional photon blockade(CPB)effect in a cavity optomagnonic system with Kerr nonlinearity.The realization of the CPB effect depends on both the Kerr nonlinearity and Kerr-like nonlinearity of the optical cavity,which is converted using magneto-optical coupling.The CPB effect can be realized in a cavity optomagnonic system with weak magneto-optical coupling by modulating the strength of the Kerr nonlinearity.Notably,our scheme supports photon blockade in both the strong and weak Kerr nonlinear regimes,which broadens the range of experimental parameters.Furthermore,we explored the parameter regimes where the CPB effect could not be achieved because of the combined effects of the magneto-optical coupling and Kerr nonlinearity.We also determined the optimal driving amplitude region for generating high-quality single-photon sources.This work not only provides a novel route for realizing the CPB effect but also establishes a versatile platform for producing single-photon sources with high purity and brightness.
