Zusammenfassung:
We investigate laser-induced quantum interference phenomena in superradiance
processes and in an ensemble of initially excited $\Lambda-$type closely packed
three-level emitters. The lower doublet levels are pumped with a coherent laser
field. Due to constructive quantum interference effects, the superradiance
occurs on a much weaker atomic transition which is not the case in the absence
of the coherent driving. This result may be of visible relevance for enhancing
ultraweak transitions in atomic or atomic-like systems, respectively, or for
high-frequency lasing effects.
