Saturation spectroscopy in optically thick three-level gas media.
High-contrast transmission spectra arising from saturated absorption in optically thick Doppler-broadened threelevel media are analyzed within the formalism of Maxwell-Bloch-type equations. It is found that although in the strong pumping engine propagation-induced line narrowing and light-shift elimination occur, spectral features lying within the natural linewidth cannot be resolved.
