Spectral and energy characteristics of a kilojoule photo-initiated HF/DF laser operating with a mixture F2-(H2+D2)-He

The theoretical and experimental study of the spectral and energy characteristics of radiation of the pulsed photoinitiated HF/DF-laser operating on the chain chemical process in the gas mixture F 2 (H 2 +D 2 ):O 2 :He=3:1:0.3:6.7 of atmospheric pressure depending on the relation between the initial concentrations H 2 and D 2 and the oscillation threshold is carried out. The optimum requirements for a simultaneous oscillation on molecules HF and DF in a wide spectral range from 2.7 up to 4.8 µm are determined in experiment and also by numerical modeling.
