On the possibility of simultaneous emission of an autonomous cw HF — DF chemical laser in two spectral ranges

The efficiencies of different fuel compositions used in the combustion chamber of an autonomous cw chemical HF — DF laser for obtaining high specific energy parameters during simultaneous lasing in HF and DF molecules in two spectral ranges are theoretically analysed. It is shown that mirrors with the reflectance above 99% in these spectral ranges can be manufactured in principle.
