Chemical laser utilizing the branched-chain stage of the oxidation of carbon disulfide

Journal Article · · Sov. J. Quant. Electron. (Engl. Transl.); (United States)
It was predicted theoretically that a mechanism of oxidation of carbon disulfide established earlier should be used to achieve lasing as a result of vibrational--rotational transitions in CO molecules formed during the explosive branched--chain stage of the CS/sub 2/+O/sub 2/ reaction. This conclusion was confirmed experimentally: a laser utilizing branching of chemical chains was constructed for the first time. Simultaneous firing of CS/sub 2/--O/sub 2/ mixtures diluted with helium of nitrous oxide (corresponding to a ''peninsula'' of chain ignition) was performed by an ultraviolet radiation pulse. Lasing appeared at the leading edge of the fast oxidation stage and it lasted for approx.1 msec. The output energy of the laser was 20 mJ and the gain was >20%/m.
