Abstract

In the recent experiment, the phenomena of superluminal and slow-light propagation in dispersive medium were found, and there are various explanation in theory. We find the phenomenon can be explained by multiple-photon interaction. Otherwise, the multiple-photon interaction can also appear other optical phenomenon: doubling frequency, sum frequency, difference frequency which are found in nonlinear optics.
