Abstract : The motivation for this study program is reviewed and factors which enter into the selection of specific molecules are considered. The molecules CO2 and NaCl are selected for parallel study and experimental approaches are devised. In the CO2 case the primary reaction studied is the oxygen-acetylene explosion, while in the NaCl case a continuous flow of sodium and chlorine gas is used. A series of experiments is described which lead to the conclusion that CO2 is the more promising molecule for a chemical laser. In one experiment it is found that conversion of chemical energy to infrared radiation during combustion is occurring at 10% efficiency in the CO2 molecule. Further experiments on chemical initiation by photolysis and electrical discharge are described. During these investigations a new laser is developed in the isotope C(12)O2(18), shifted by 11% from the ordinary CO2 laser. The results of experiments to generate high power in gaseous CF2I by flash photolysis are also reported.
