Dynamic suppression of spontaneous emission
Spontaneous emission can be modified if the atom is driven by an external coherent field. Such modification include the three-peak spectrum of resonance fluorescence from a two level atom. The spectral line elimination and cancellation of spontaneous emission is possible under conditions that the spontaneous emission from an excited atom can be trapped in the upper states without decaying. The amount of fluorescence in this case as well as the population of the upper levels can be controlled. If spontaneous emission along with atomic transition is suppressed, it is possible to create a population in version on this transition by using a very weak incoherent pumping.
