Abstract

We analyse saturated-absorption and two-photon absorption line shapes in Doppler-broadened three-level systems with nearly degenerate resonance frequencies. The two counterpropagating equal-frequency laser beams of arbitrary intensity irradiating the sample are allowed to couple to both atomic transitions. Various Doppler-free resonances associated to two- and three-photon effects occur. Their saturating behaviour is analysed. A comparison is made with experiments by Woerdmann and Schuurmans and by Himbert et al. © 1985 Società Italiana di Fisica.
