Abstract The most accurate measurements in physical sciences will be precision spectroscopic experiments which are based on the usage of most narrow lines in cooperation with interference phenomena. We present a novel experimental observation of ``a sharp absorption resonance line'' with much more broad laser lights. The mechanism of such a novel phenomenon will be elucidated and its implications will be discussed.
