Stochastic Models of Intermediate State Interaction in Second Order Optical Processes: Stationary Response. II

The stochastic theory of intermediate state interaction developed in a preceding paper is applied to more realistic models to discuss the correlation between the incident and the scattered photons in more detail. Through these model calculations it is confirmed that the spectral characteristics of the second order optical process are determined by a few physical parameters of the radiative damping rate and the modulation amplitude and rate. In the slow modulation limit the relative intensity ratio between the broad Raman component and the luminescence is almost determined by the ratio between the radiative damping rate (γ_b) and the modulation rate (γ_m). In the fast modulation limit the ratio between the δ-shaped Raman component if it exists and the luminescence is given by the ratio between γ b and the dephasing relaxation rate Δ²/γ_m (Δ denotes the modulation amplitude.).
