Description
Summary:The transient evolution of the susceptibility of the spherical quantum dot with an on-center hydrogen impurity, interacting with the continuous wave lasers, with respect to the probe field is studied numerically and analytically by solving optical Bloch equations. The influence of the control Rabi frequency, dephasing rates and laser detunings is discussed. The damped oscillatory behaviour is observed, as well as the amplification of the probe laser light before the stationary regime of the electromagnetically induced transparency is achieved.
