Abstract
A chemical laser having means for repeatedly circulating the gaseous working medium in a portable, self-contained system is disclosed. An excited laser species is formed by chemical means and after passing through the optical cavity, the working medium is purified by selective absorption and adsorption processes, increased in pressure, supplemented with makeup feed reactants and recycled. The operation of a system using deuterium and sulfur hexafluoride gases is discussed in detail although various combinations of other suitable reactants which provide a halogen and hydrogen or an isotope thereof are disclosed.
