Popis: Abstract— A working process is proposed for an HF(DF) laser, in which evacuation of the reactor is completely excluded. The workflow consists of the following stages: (1) displacement of the reaction products, which are formed after initiation of the working mixture, by an inert gas and (2) subsequent displacement of the inert gas by the working mixture. A design solution is proposed for the system of gas puffing into the reactor. Gas is supplied through an annular slot at one of the reactor ends, which makes it possible to minimize the consumption of inert gas used for displacing the reaction products after initiation of the working mixture. The amount of residual HF(DF) gas in the reactor is incapable of affecting the generation energy in the next cycle. It has been experimentally shown that the displacement technology does not lower the lasing energy in comparison with the pumping technology, but significantly reduces the duration of the HF(DF)-laser operating cycle by approximately two orders of magnitude).
