Title: Optimisation of characteristics of a chemical HF laser operating by using a new method for oxidising-gas production

Abstract

The energy parameters of an HF laser operating by using a new method for oxidising-gas production, which is based on the principle of two-region mixing, are optimised. The total amount of the inert diluent (helium) supplied to the laser was varied during experiments by varying its relative fraction only in the second mixing region. For an optimal relative fraction of the diluent in the second mixing zone and for an optimal position of the optical axis of the cavity under a constant pressure in the gas generator, the laser radiation power and the specific power output could be increased by 50% and 60%, respectively, compared to the laser operation regime realised in our previous experiments. In this case, the inert diluent amount decreased by 35% and the length of the generation region increased by 20%. (lasers)
