ABSTRACT:
A combustor using D.sub.2 /NF.sub.3 /He is used in a laser gain generator in a cylindrical gas laser. The combustor includes a plurality of primary rings having fuel, oxidizer and diluent orifices therein. Fuel and oxidizer orifices form a triplet injector set that provides a reactant set. Two diluent orifices form a diluent injector set that provides a diluent set. These sets alternate about each primary ring and from one primary ring to the adjacent primary ring. Because the diluent set does not mix directly with the reactant set initially, a greater percentage of lasing products are formed because of the higher temperature in the reacting zone. Diluent is mixed as required at a later stage in the flow.
