Query: Incoherent control of electromagnetically induced transparency and
  Aulter-Townes splitting   The absorption and dispersion of probe light is studied in an unified
framework of three-level system, with coherent laser driving and incoherent
pumping and relaxation. The electromagnetically induced transparency (EIT) and
Autler-Townes splitting (ATS) are studied in details. In the phase diagram of
the unified three-level system, there are distinct parameter regimes
corresponding to different lineshapes and mechanisms, and the incoherent
transition could control the cross-over between EIT and ATS. The incoherent
control of the three-level system enables the investigation of various
phenomena in quantum optics, and is beneficial for experiments of light-matter
interactions.
