Chemical laser emitting simultaneously from excited HF and DF molecules

Performance has been investigated of a broadband chemical laser utilizing chain and nonchain reactions and emitting simultaneously from excited HF* and DF* molecules. Simultaneous stimulated emission of radiation in the spectral ranges of 2.7 - 3.0 micrometer and 3.7 - 4.1 micrometer has been obtained. Theoretical dependencies are presented of laser energy characteristics on the ratio of initial H 2 and D 2 concentrations in a working mixture.
