饱和吸收和“慢光”

Saturable absorption and 'slow light'

Adrian C Selden

摘要:

对最近一些基于相干布居振荡(CPO)的“慢光”实验的定量评估表明,它们可以更简单地解释为饱和吸收现象。因此,它们并没有提供“慢光”的明确证明。实际上,通常不满足光谱带宽的限制条件,使得不满足在均匀加宽的吸收线中燃烧窄光谱孔的要求。本文从饱和吸收体的相移和脉冲延迟的分析出发,提出了一些确定性的“慢光”现象的检验方法

英文摘要:

Quantitative evaluation of some recent 'slow light' experiments based on coherent population oscillations (CPO) shows that they can be more simply interpreted as saturable absorption phenomena. Therefore they do not provide an unambiguous demonstration of 'slow light'. Indeed a limiting condition on the spectral bandwidth is not generally satisfied, such that the requirements for burning a narrow spectral hole in the homogeneously broadened absorption line are not met. Some definitive tests of 'slow light' phenomena are suggested, derived from analysis of phase shift and pulse delay for a saturable absorber
