Abstract
We consider spontaneous emission in a four-level atomic system driven by three fields. It is shown that by controlling the phase and the amplitude of the driving fields a wide variety of spectral behavior can be obtained, ranging from a very narrow single spectral line to up to six spectral of varying widths.
