Power broadening of electromagnetically induced transparence resonance

The width of an electromagnetically induced transparency (EIT) resonance is studied theoretically for an ideal three-level system in a L-type configuration. The optical Bloch equations are solved and the power broadening behavior of the EIT resonance is studied as a function of both couple and probe laser intensities over a broad range. It is shown that at relative low couple laser intensity there is a quadratic dependence of the EIT width on the couple laser Rabi frequency and at large couple laser intensity the EIT resonance evolve into the well known dynamic Stark splitting and its width has a linear dependence on the couple Rabi frequency. The dependence of the EIT width on the probe laser intensity shows different characteristics with the dependence on the couple laser intensity. Furthermore, the probe laser causes saturation and this is also discussed in this paper.
