A semi-classical model (classical by the field and quantum by describing biomolecules) is proposed, which establishes the dependence of the DNA/RNA dimerization rate on ultraviolet C (UVC) radiation intensity. The two types of cooperative effects between the converted photons in these multiple steps of Raman lasing are proposed. The first type involves the cooperative process between the photons of one of the steps of Raman conversion. The second cooperative effect appears between the photons belonging to different steps of multiple conversions. This new type of generated coherent state is proposed by novel bimodal entangled sources, which take into consideration both the coherence and collective phenomena between the photons belonging to the system of the bimodal field obtained in multiple Raman emission. The application of higher-order multiple Roman bimodal coherent field quantum information is described in accordance with the definition of quantum amplitude and phase of such entangled states of light.

Cooperative phenomena in a radiating system have been discussed by Dicke. A new formulation of the theory is presented, which shows more clearly the relations of these effects with the quantum-mechanical identity principle. Some theoretical and practical implications of the theory are pointed out.
