This study examines the coherence properties among the Stokes and anti- Stokes fields and their applications in Communications. We investigate a novel two-photon entangled sources approach which takes into account the coherence and collective phenomena between the fields. The quantum propriety of realistic sources of powerful coherent bi-boson radiation (coherent entanglement of Stokes and anti-Stokes photons) is analyzed. Finally, we examine experimental applications of coherence between the Stokes and anti-Stokes photons obtained in super-radiance and resulting lasing effects in quantum communications and cryptography.
