Abstract
We have measured the time delay of a P (20) short pulse propagating through a high−pressure CO2 amplifier under small−signal−gain conditions. The reduced velocity agrees with the group velocity, which is about 0.92c. The effect is proportional to the small signal gain divided by the linewidth.Keywords
