Enhanced Raman scattering can be obtained by the initially prepared atomic spin excitation, or by injecting a seeded light field which is correlated with the initially prepared atomic spin excitation. This paper theoretically calculated the quantum fluctuations of the quadrature components of the two-mode photon-atom quantum interface and found that the enhanced Raman scattering based on coherence can improve the initial photon-atom squeezing slightly in a certain scope, and correlation-enhanced Raman scattering can produce strong two-mode squeezing of photon-atom. Such a strong two-mode squeezed state at the photon-atom interface has very important applications in precision measurement research based on the light field and atomic system.
