We study the evolution of quantum entanglement in double cavity systems. The entanglement of cavity atoms induced by entangled pair of photons is investigated. Both entanglement sudden death and entanglement sudden birth phenomena are shown to exist and are analyzed in detail. We also propose a strategy to enhance the entanglement between the atom in one cavity and the photon in another cavity by using quantum Zeno effect.

We investigate the optical limiting behavior exhibited by a resonant dense medium when inserted in a ring cavity. The influence of the cavity parameters, the atomic frequency detuning and the density of atoms are determined.
