Abstract
The entanglement of two two-level atoms with the nondegenerate two-photon transitions interacting with two-mode thermal field in lossless cavity has been considered. The possibility of entanglement degree growth in the presence of an atomic coherence and direct dipole-dipole interaction of atoms has been derived.
