Abstract
We examine the absorption of a weak probe beam for a V-type atom with a closely spaced doublet and demonstrate that quantum interference bet ween the two excitation pathways can result in very narrow resonances, transparency, and even gain without population inversion. The origin of these effects is discussed.
