Wide-band chemical laser utilizing both HF* and DF* excited molecules

The operation was studied of a wide-band chemical laser utilizing chain and nonchain reactions and emitting due to both HF* and DF* excited molecules. Radiation was emitted simultaneously in the 2.7–3.0 μm and 3.7–4.1 μm spectral ranges. The dependences of the laser energy characteristics on the ratio of the initial H₂ and D₂ concentrations in the active mixture were calculated.
