This first semi-annual report summarizes the progress made to date in the generation of tunable infrared radiation and its application to remote pollutant detection by the differential absorption method.nAt the laser Radar Conference in Sendai, Japan held recently, it was recognized that future remote pollutant measurements depended critically on the availability of high energy tunable transmitters. Furthermore, due to eye safety requirements, the transmitted frequency must lie in the 1.4 urn to 13 urn infrared spectral range.
