Abstract
Abstract Reactions of the type QAx -> Q + xA A + BC -> AB* + C initiation WHERE Q, A, B and C are atoms, are driven by means of a very fast explosive reaction which does not produce the lasing molecule AB* but rather drives the lasing reaction by providing copious quantities of the atomic species A to undergo the lasing reaction. Provided that a sufficient distance in the binding energies of A''s molecular precursor QAx and BC exists, so that QAx is selectively dissociated, intiation of a rapid explosive reaction in a gaseous branching chain explosive mixed with QAx and BC produces an intense laser pulse chain in an optical cavity.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
101 words
A method of producing an intense laser puLse through reactions of the type QFx -> Q + xF F + HC -> HF* + C where Q, F, H, and C are atoms, Q is bromine, chlorine, nitrogen, or sulfur, H is hydrogen, F is fluorine, and C is hydrogen, chlorine, bromine, sulfur or nitrogen, comprising selectively and substantially completely dissociating QFx in a gas mixture comprising QFx, HC, and a branching chain explosive by initiating a rapid explosive reaction in said explosive, said explosive generating no HF as a reaction product, and said gas mixture being in an optical cavity.
Claim 2
Independent Claim
101 words
A method of producing an intense laser puLse through reactions of the type QFx -> Q + xF F + HC -> HF* + C where Q, F, H, and C are atoms, Q is bromine, chlorine, nitrogen, or sulfur, H is hydrogen, F is fluorine, and C is hydrogen, chlorine, bromine, sulfur or nitrogen, comprising selectively and substantially completely dissociating QFx in a gas mixture comprising QFx, HC, and a branching chain explosive by initiating a rapid explosive reaction in said explosive, said explosive generating no HF as a reaction product, and said gas mixture being in an optical cavity.
Claim 3
Dependent Claim
20 words
The method of claim 9 wherein Q is sulfur or nitrogen, and HC is H2, HCl, HBr, H2S or H3N.
Claim 4
Dependent Claim
13 words
The method of claim 2 wherein QFx is SF6 and HC is H2.
Claim 5
Dependent Claim
23 words
The method of claim 3 wherein said gas mixture is 24 mole percent ClN3, 19 mole percent SF6, and 57 mole percent H2.
Claim 6
Dependent Claim
13 words
The method of claim 2 wherein QFx is NF3 and HC is H2.
Claim 7
Dependent Claim
23 words
The method of claim 5 wherein said explosive is ClN3 and said explosive comprises 12 to 25 mole percent of said gas mixture.
Claim 8
Dependent Claim
40 words
The method of claim 6 wherein said gas mixture comprises 25 mole percent ClN3, 25 mole percent NF3, and 50 mole percent H2, and wherein the pressure of said gas mixture is in the range of 12 to 24 torr.
Claim 9
Dependent Claim
15 words
The method of claim 1 wherein said rapid explosive reaction is initiated by optical radiation.
Claim 10
Dependent Claim
28 words
The method of claim 8 wherein the optical radiation used to initiate said explosive reaction is in a spectral range to which QFx and HF are essentially transparent.
