Abstract
We study the absorption spectrum of a V-type three-level atom when the lase r beam interacts only with one of its two transitions. With the presence of vacuum-induced quantum interference, the absorption spectrum shows some ne w interesting features, which include ultranarrow absorption line, transpar ency, and a reverse-saturated absorption that is characterized by a larger absorption with increasing laser intensity.
