The be-quanta generation and the coherent process of the light at two-photon emission it's a new type of the coherence which can be realized between pairs of the particles [14]. This possibility of the emission can be realized in the two-photon laser and maser. The first experiments demonstrate this realization [10]. In this paper it is propose a new system of the kinetic equations which describes the non-coherent and be-quanta coherent emission which take into account emissions and the transition from spontaneous to induced emissions in the system. It is studied the rate of the emission as function of this parameters [17]. It is demonstrate mono-photonics losses from the resonator drastically destroy the coherence between the be-photons
