| Abstract: | This paper investigates the breaking point between fast-and slow-light in a degenerate two-level atomic system, wherefast-light can be converted to slow-light arbitrarily on a singletransition line by adjusting the strength of the pumping field. Anequivalent incoherent pumping rate is introduced in this simplifiedtheoretical model which exploits the dependence of this feature. Theexperimental observation is presented as evidence of the breakingpoint where the injected power is about 0.08~{rm mW}. |
