Total fluorescence inhibition via incoherent dressed population transfer

The resonant fluorescence spectrum of three coherently coupled excited states to the ground state is evaluated analytically in the strong driving field approximation. One of the three dressed states can be stabilized by quantum interference. We show that it is possible to transfer excited state population from the two decaying dressed states to the nondecaying dressed state via an appropriate choice of incoherent pumping processes. This allows almost complete inhibition of the total fluorescence, even in the presence of deleterious spontaneous emission processes.
