Abstract
The absorption of a weak laser beam probing a Doppler-broadened three-level system saturated by a standing-wave pump is studied theoretically for the case of small saturator detunings. The features of the obtained absorption spectra are analysed by means of the dressed-atom approach. A strong influence of radiative and high-order multi-photon processes is showed. The influence of saturator tuning fluctuations on the narrow Doppler-free peak which appears in the resonant case is analysed and its consequences for high-resolution applications are considered. © 1985.
