Transparency Induced by Two-Photon Coherence in the V-ShapedThree-Level System
-
Abstract
We have investigated th steady-state behavior of a V-shape three-level system submitted to the radiative field and to the relaxation process. The coherence induced by simultaneous two-photon transition leads to a strong decrease of medium absorption. In this case, the peak of transparent spectrum is 7 times higher than that of saturant spectrum. -
