摘要：

Two-photon absorption is theoretically analyzed within the semiclassical formalism of radiation-matter interaction. We consider an ensemble of inhomogeneously broadened three-level atoms subjected,to the action of two counterpropagating fields of the same frequency. By concentrating in the limit of large detuning in one-photon transitions, we-solve perturbatively the Bloch equations in a non-usual way. In this way. we derive an analytical expression for the width of the two-photon resonance that makes evident sub-Doppler two-photon spectroscopy. We also derive an analytical expression for the Stark shift of the two-photon resonance.
