"Having selected three models, which describe quantum features of nonlinear optical processes, we reflect on some methods for the resolution of descriptions of these processes. So the corresponding classical solution can be used for obtaining the quantum statistics to the first order in the bosonic commutator. Depending on the simplicity of the optical process and the role played by few-photon states, the invariant-subspace method has also been long used for calculations. On the contrary, the appropriate Heisenberg picture must approach the dull powers of the time variable by its interesting harmonic time dependences in the limit of large available computer memory." . . . .
