✦ Synopsis

Dynamics of a three-level quantum system in
Λ-configuration 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.
