Inhomogeneous line profiles

We will now discuss saturation of inhomogeneous line profiles. As an example we treat Doppler-broadened transitions, which represent the most important case in saturation spectroscopy.

In Fig. 2.7 the differences in the saturation behavior of a homogeneous (Fig. 2.7a) and an inhomogeneous line profile are illustrated. For the inhomogeneous case two situations are illustrated ...
