“…On the other hand, repetitively operated, self-contained HF lasers have always been a research focus, as in most cases, repetitive operation of a closed system is required. For repetitive operation, the pulse energy is faced with severe degradation along with the output pulse number [13][14][15][16][17]. Firstly, the concentration of the reactant gases declines as they are decomposed during every discharge.…”

Pulse energy sustainability of a burst mode closed-cycle pulsed HF laser is investigated with a simple theoretical model considering gas replenishment and chemical scrubbing. The effects of reactant gas consumption and de-excitation of excited HF by ground state HF are studied quantitatively. Also, experiments are carried out for comparison and validation. Simulation and experiments show that, in the burst mode operation, the energy loss caused by gas consumption is about 0.06-0.12 mJ per pulse while that induced by the de-excitation process is about 0.22-0.29 mJ per pulse, demonstrating that chemical scrubbing should play a more important role in the energy preservation of non-chain pulsed HF lasers.

“…But special investigations into improvement of the efficiency did not perform. As a rule, electrical efficiency (relative to stored energy) of the non-chain DF and HF lasers is not higher η 0 =3-4% [1][2][3][4][5] . One of the reasons limiting the efficiency is development of discharge non-uniformities 6 .…”

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 =5-6% with the output over 1 J was demonstrated for the first time.
