The Application of Stimulated Raman Gain and Inverse Raman Spectroscopy to the Remote Detection of Chemical Agents

Abstract : The use of inverse Raman spectroscopy/stimulated Raman gain for the remote detection of chemical agents is analyzed. The sensitivity of this technique is calculated for ranges 1 and 10 kilometers and target cloud widths of 10 and 50 m. The sensitivity is also shown to decrease tremendously as the agent or target cloud moves away from the focal point of the laser.
