  We consider the coherent state radiation field inside a micromaser cavity and
study the entanglement mediated by it on a pair of two level atoms passing
though the cavity one after the other. We then investigate the effects of
squeezing of the cavity field on the atomic entanglement. We compute the
entanglement of formation for the emerging mixed two-atom state and show that
squeezing of the cavity radiation field can increase the atomic entanglement.
