For instance, if a soldier is being sent into an area with potential hazards, the ability to detect certain hazardous gases from distances up to 1 kilometer away could save them. DRS research involves utilizing a long wave infrared (LWIR) laser to excite trace molecules of interest while simultaneously using a Terahertz (THz) source to probe the excited gas to detect the transient change in molecular population due to the excitation from the LWIR laser. We then use this data to further our understanding of the underlying molecular physics to forecast double resonance behavior in different situations. This technique has been studied at low pressures and bringing it to atmospheric pressure opens up a world of opportunities.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div
