Investigation of concept of efficient short wavelength laser. Final technical report, April 1, 1977-July 31, 1979
The feasibility of producing an efficient, short wavelength, storage laser for ICF driven applications by making use of certain state-specific reactions of exoergic azide compounds has been investigated. The ultraviolet (approx. 300 nm) photolysis of gaseous ClN/sub 3/ produced prompt emission in the red, which was attributed to the efficient formation of ClN(b/sup 1/..sigma../sup +/) with subsequent ClN(X reverse arrow b) fluorescence. Based on these results, a small-scale laser demonstration experiment was constructed using short duration Xe flash lamps as the photolytic source. The results of this latter experiment were negative. The most plausible explanation was that the flash lamps provided sufficient far-uv radiation to dissociate and/or ionize the ClN(b) produced in the primary photolytic step. In parallel, limited experiments were performed on the rapid pyrolysis of a solid, ionic azide, NaN/sub 3/, to produce gaseous N/sub 3/ radicals and subsequent production of triplet N/sub 2/ molecules.
