We propose a scheme to generate four-mode multiphoton entangled states by passing N identical atoms through two high-Q cavities in turn. In the case of N=1, the scheme can deterministically generate Einstein-Podosky-Rosen entangled photon pairs. We use adiabatical state evolution under large atom-cavity detuning, so the scheme is insensitive to atomic spontaneous decay. The influence of cavity decay on fidelity and success probability is also discussed.
