Abstract

Effect of pumping pulse duration and specific input energy on the output of discharge non-chain HF (DF)-lasers is studied using excitation by inductive and LC-generators. Experimental conditions providing maximal performance of discharge non-chain HF- and DF-lasers are determined. High discharge uniformity obtained with the use of special shaped electrodes along with uniform UV preionisation was found to be key parameter for improving efficiency of discharge HF (DF)-laser. Intrinsic efficiency of HF and DF lasers up to η_in~10 % and 7%, respectively, is obtained in the SF₆-H₂(D₂) mixtures. With the LC-generator, maximal total efficiency of the lasers up to η₀=6% was obtained and the output over 1 J was realized.
