Gain-Swept Superradiance Applied to the Stand-Off Detection of Trace Impurities in the Atmosphere

We show that gain-swept superradiance can be used to detect low (parts per million) concentrations of various gases at distances on the order of kilometers, which is done by using pulse timing to create small regions of gain at positions that sweep toward a detector. The technique is far more sensit...
