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 sensitive than previous methods such as light detection and… (More)
Airborne contaminants, e.g., bacterial spores, are usually analyzed by time-consuming microscopic, chemical, and biological assays. Current research into real-time laser spectroscopic detectors of such contaminants is based on e.g., resonance fluorescence. The present approach derives from recent experiments in which atoms and molecules are prepared by one… (More)
We demonstrate a new method for measuring translational temperatures using degenerate four-wave mixing (DFWM). We perform high-resolution measurements of DFWM spectra in both the forward (BoxCARS) and backward (phase-conjugate) phase-matching geometries on nitric oxide (NO) in a room-temperature gas cell. We analyze the spectra with a modified perturbation… (More)
