Abstract:

Spectral parameters of non-chain chemical laser on mixtures of hydrogen and deuterium with SF6 pumped by a discharge with UV illumination from generator with inductive energy storage and by a diffuse discharge formed in a non-uniform electric field due to preionization by run-away electrons (REP DD) are compared. It is shown that high uniformity of volume discharges formed in the active laser medium allows the increase in the number of laser lines. Therewith intense cascade transitions appear in the laser spectra and lasing efficiency on HF (λ = 2.8÷3.2 mm) and DF molecules (3.8÷ 4.2 mm) reaches its ultimate value. It is shown that the volume discharge initiated by run-away electrons (REP DD) in gas mixtures with SF6 is an efficient pumping method of lasers on HF(DF) molecules.

Keywords:
