What is Lamb-dip line shape symmetrisation based on the position of the active medium in the cavity: Modelling about?

We show that with an adequate choice of geometric parameters, such as the position of the active medium in the cavity, it is possible to design a laser cavity where the lens effects due to population and saturation inhomogeneities would be simultaneously minimized. Associated with an absorbing cell and using the technique of saturated absorption, such a cavity will generate symmetrical output line shape where the frequency of the Lamb-dip coincides with the central frequency of the laser. We believe that it would be advantageous for such a cavity to replace the stabilized lasers commonly used in different fields of physics such as, for example, spectroscopy.
