我们报告了在光密热铷气体（大约 360 K）中观察到的小群速度为 90 m/s 的量级和大于 0.26 ms 的大群延迟。这种介质在非常弱的光场和非常尖锐的光谱特征之间产生强烈的非线性相互作用。该结果与之前关于致密相干介质非线性光谱的研究结果一致。
We report the observation of small group velocities of order 90 m/s and large group delays of greater than 0.26 ms, in an optically dense hot rubidium gas (approximate to 360 K). Media of this kind yield strong nonlinear interactions between very weak optical fields and very sharp spectral features. The result is in agreement with previous studies on nonlinear spectroscopy of dense coherent media.
