Oscillations in a three-level pump-probe configuration: dressed-state quantum beats

Not Accessible

Abstract

Quantum beats can be observed when an atomic system is prepared in a coherent superposition of eigenstates. It manifests the most basic concept of quantum mechanics: coherence, and has been studied extensively. The common configuration for studying quantum beats is that a three-level system interacts with a pulse excitation, where either upper or lower level can be a closely- spaced doublet [1], We report here a new type of quantum beats, dressed-state quantum beats, observed in a three-level pump-probe configuration (Fig. 1). The three-level system and experimental detail can be found elsewhere [2].
