摘要： The Doppler-free optical-optical triple-resonance(DF-OOTR) spectroscopy and its line-shapes have been studied in detail theoretically and experimentally. The line center, linewidth and lineshape of an isolated DF-OOTR spectra component have been derived by using density matrix motion equation describing the interaction of a three-level system with three optical fields. The variations of the lineshape symmetry, the relative position and the strength of the Doppler-free Lorentzian dip to its background are comparable to the experimental traces varying with the relative intensities of the two mutual-saturating probe laser beams, as well as with the detuning of the first pumping laser from the intermediate level. The DF-OOTR technique shows a distinguished advantage especially in the labeling of the transitions and in the determination of absolute position of the upper level affected by perturbation shift, as these happened often in the dense molecular highly excited states.
