Efficient discharge-pumped non-chain HF and DF lasers

摘要

Discharge and laser parameters in mixtures of SF_6 with H_2 and D_2 are studied using inductive and LC-generators. Excitation pulse parameters providing ultimate performance of discharge non-chain HF- and DF-lasers are determined. Processes affecting efficiency of the lasers are discussed. Ultimate intrinsic efficiency η_(int) of the HF and DF lasers up to 10 % and 7%, respectively, was realized in the SF_6-H_2 (D_2) mixtures. Electrical efficiency of the lasers up to η_0=6,4% with the output up to 1,5 J was demonstrated for the first time.
