Interaction of three-level atoms with stochastic fields
Résumé
Three broadband laser pulses are used to drive transitions between three levels in Sr vapor. A four-wave mixing signal is monitored as a function of the delay time t12 between two of the pulses. For sufficiently strong fields, it is found that the signal, as a function of t12, can possess a dip or a spike which is narrower than the correlation time of the radiation fields. A theoretical interpretation of the results is presented in terms of the so-called dark resonance.
