AMPLITUDE CONTROL OF SPONTANEOUS EMISSION
Rizwan Ahmed, Tasnim Azim
Abstract
We study the control of spontaneous emission in four-level atomic system driven by two fields. We show that with the variation of dynamical variable, namely, Rabi frequency, a wide variety of spectral behavior can be obtained, including extreme spectral narrowing. In our system, the spectrum of the spontaneous emission is independent of the phase associated with microwave field.
