The properties of these equations are analysed by adopting an approximation higher than the quasi-static approximation, provided the molecules are far from resonance.

It is shown that no additional threshold condition is required for the anti-Stokes components, i.e., the stimulated anti-Stokes radiations make their appearance as a matter of fact in the stimulated Raman effect. Under certain conditions, there exists only one stable equilibrium point, at which the Stokes and anti-Stokes light appear with equal intensity, when the Raman-active medium is pumped by an intensive laser beam.
