解釋
光譜線寬-
In this paper we have done two work, one is we, in the dressed states representation, reveal that the constructive interference of atomic coherence on absorption leads to electromagnetically induced absorption, which is in sharp contrast to the case in which destructive interference of atomic coherence gives rise to electromagnetically induced transparency and the other is we reveal that coupling field linewidth inhibits electromagnetically induced absorption, by employing a four - level system in which three transitions are in n configuration and the middle transition serves as a probe transition
