Abstract

Abstract

The de-excitation effect of ground state DF molecules after dicharge of no-chain pulsed DF laser to excited DF molecules is an important cause for laser's steady working. In order to solve this problem, molecular sieves of 3A and 5A were respectively used as the adsorbent for experiments. Without molecular sieve, the laser output power decreased to 56% of initial power after 1 000 repetitive pulses. After 3A and 5A molecular sieve being utilized, the decrease of laser power were less than 20% after 5 000 and 6 800 shots respectively, so the stability of the laser has been greatly improved. The results show that the adsorptive efficiency of 5A molecular sieve is higher than that of 3A molecular sieve. And these two molecular sieves adsorbed not only the ground DF molecules, but also reacting gas. So the stability of laser can be improved by supplementing of reacting gas timely.
