Dynamics of a three-level quantum system in Λ-cofiguration driven by a resonant laser field with and without frequency modulation (FM) is studied for the first time in detail using two simulation techniques - the density matrix and quantum trajectories analysis. This analysis was applied to the FM-spectroscopy of coherent dark resonances in Cs atoms and computer simulation results for the absorption spectra are in qualitative agreement with those taken in an experiment. A graph is presented. Mechanism of forming the dark resonances for the case of the Λ-system interacting with the frequency-modulated laser field. © 2006 by Astro Ltd.

Abstract

Dynamics of a three-level quantum system in Λ-cofiguration driven by a resonant laser field with and without frequency modulation (FM) is studied for the first time in detail using two simulation techniques - the density matrix and quantum trajectories analysis. This analysis was applied to the FM-spectroscopy of coherent dark resonances in Cs atoms and computer simulation results for the absorption spectra are in qualitative agreement with those taken in an experiment.
