Abstract
Abstract Apparatus is disclosed which can continuously mix indefinitely large volumes of gases in characteristic times that are short compared to characteristic collisional relaxation times for the excitation energy for the component gases. The present technique has application to flowing gas laser systems in that it provides a means to mix large volumes of gases together to initiate an energy exchange process between the mixing atomic or molecular components, or to initiate a chemical reaction involving the mixing of reactant components to form product atoms or molecules in an excited state.
