We propose a scheme for preparing multiple-photon GHZ state via cavity-assisted interaction. There are n -pair single-photon pulses successively injected and reflected from two sides of the cavity, which traps one atom. After the atomic state is measured, a 2 n -photon GHZ state is produced. In the ideal case, the successful probability of the scheme is close to unity.
