ResumoDoppler-free resonances in saturated absorption on the D2 line 85Rb are investigated by using a tunable external-cavity-diode laser. The linewidths of the most prominent crossover resonances are investigated as a function of the saturating beam intensity. In spite of the fact that many levels and different mechanisms of optical pumping are involved in the saturation, the dependences are found to fit well the simple formula, obtained for a two-level system with a phenomenologically defined saturation parameter.
