Abstract: A catalyst bed containing alumina pellets on which an active catalyst metal selected from iridium, nickel, niobium, and molybdenium has been deposited is employed to decompose a compound selected from deuterohydrazine, deuteroammonia, hydrazine, and ammonia to yield ammonia free deuterium and nitrogen or hydrogen and nitrogen at a temperature required for immediate use in a DF or HF laser which uses F atoms as the fuel. The decomposition temperature of the catalyst bed is maintained by a hypergolic reaction produced from reacting a fuel selected from the group consisting of hydrazine, methylhydrazine, 1,2-dimethylhydrazine, and blends of the same with an oxidizer selected from the group consisting of inhibited red fuming nitric acid, dinitrogen tetroxide, chlorine trifluoride, and chlorine pentafluoride. A laser employing ammonia free decomposition products of hydrazine and ammonia produced at a temperature between about 500.degree. C. and 900.degree. C. operates at a higher power output.

Abstract: A cyano compound fuel selected from the group consisting of dicyanoacetylene (DCA), tetracyanoethylene (TCE), and tetracyanoethylene oxide (TCEO) when reacted with an oxidizer compound selected from the group consisting of fluorine (F.sub.2), nitrogen trifluoride (NF.sub.3), chlorine trifluoride (ClF.sub.3), chlorine pentafluoride (ClF.sub.5), and tetrafluorohydrazine (N.sub.2 F.sub.4) produces the F.sup.. atom concentration required for either HF or DF lasers. The reaction is accomplished in the presence of a diluent gas selected from nitrogen and helium. No deactivation species are among the gaseous species produced which include CF.sub.4, F.sup.. atoms, and N.sub.2 ; therefore, deactivation of the excited molecules, either HF or DF, which are responsible for the lasing in a HF or DF laser is prevented. A higher performance of the laser device can be achieved.

Abstract: The use of methoxylamine hydrochloride (CH.sub.3 ONH.sub.2. HCl) as an adive to exothermally decomposing liquid monopropellants such as hydrazine and hydrazine water mixtures to lower the freezing point of the monopropellants and thereby render the monopropellants usable in gas generators at very low temperatures.

Abstract: The use of methoxylamine nitrate (CH.sub.3 ONH.sub.2.NHO.sub.3) as an addve to exothermally decomposing liquid monopropellants such as hydrazine and hydrazine water mixtures to lower the freezing points of the monopropellants and thereby render the monopropellants usable in gas generators at very low temperatures.

Abstract: The use of methoxylamine perchlorate (CH.sub.3 ONH.sub.2.HClO.sub.4) as an dditive to exothermally decomposing liquid monopropellants such as hydrazine and hydrazine water mixtures to maintain energetic monopropellants and at the same time lower the freezing point of the monopropellants, thereby rendering the monopropellants usable in gas generators at very low temperatures.
