ABSTRACT

This chapter analyzes the methods and approaches used in the creation of pulsed and P-P non-chain HF (DF) lasers with high radiation energy. The energy characteristics of The chemical lasers (CL) are record-breaking among the whole class of gas lasers. The principle of the non-chain HF(DF) CL is based on the fact that in a laser working medium, which is a stable mixture of fluorine and hydrogen-containing gases, a non-chain reaction is initiated by the input of energy from an external source. Molecules of the starting materials dissociate to form chemically active centres, the reactivity of which is many times greater than the reactivity of the starting materials. The method based on the dissociation of fluorine-containing molecules by electron impact, carried out in a self-sustained volume discharge, has the greatest advantages over all other methods of initiating non-chain chemical reactions.
