Chemical lasers utilizing mixtures of fluorine or nitrogen fluorides with deuterium

A spectroscopic investigation was made of the stimulated radiation emitted by excited DF molecules generated by chemical reactions in D₂ + F₂, D₂ + NF₃, D₂ + N₂F₄, and D₂ + FNO₂ mixtures at pressures of ~1 torr. It was found that the largest number of stimulated emission lines (including those in the 1–0 band) was emitted by the laser utilizing the D₂ + NF₃ mixture. A study of the time dependences of the intensities of various lines made it possible to explain the features associated with cascade transitions and with the rise of the temperature of the mixture during a reaction.
