Abstract
As is well known, nonlinear laser techniques provide means for high-resolution atomic and molecular spectroscopy. The power of these techniques can be further increased when they are applied to coupled three-level systems. In the present paper new high-resolution techniques developed in optically pumped molecular lasers are described. They refer to both Doppler-Doppler and Doppler-homogeneous folded configurations. Velocity-selective excitation yields Doppler tuning of the coupled transitions; sub-Doppler saturation features generated in the absorption can be observed in the reemission. In some cases resolutions beyond the limitations imposed by the homogeneous linewidths in two-level spectroscopy are achieved.
