Paper Abstract

Amplitude-temporal and spectral parameters of laser radiation and electric discharge parameters in gas mixtures of SF6 with hydrogen and hydrocarbons are studied. Experimental conditions providing high intrinsic efficiency of a non-chain HF laser are determined. The laser efficiency with respect to deposited energy up to ηin ~ 10% is obtained using discharge excitation by inductive and capacitor generators in SF6-H2 mixtures. High discharge uniformity obtained with the use of special shaped electrodes along with uniform UNV preionization is key parameter for improving intrinsic efficiency of discharge HF-laser. There with output spectra of the HF laser significantly widens and cascade laser action on some rotational lines of the vibrational transitions of HF molecules v(3-2) → v(2-1) → v(1-0) is observed. Specific output of the non-chain HF-laser over 8 J/l (140 J/lxatm) and total laser efficiency η0~4,5% were achieved, as well.
