Abstract
Abstract A method and apparatus for producing metal atom oxidation lasing wherein an explosively shocked grooved metal plate produces metal vapor jets directed through an appropriate gaseous oxidizer. Reaction of the metal vapor with the oxidizer produces molecular species having a population inversion therein.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
62 words
IN A METHOD OF FORMING MOLECULAR SPECIES HAVING A POPULATION INVERSION THEREIN BY ATOMIZING A METAL AND MIXING THE ATOMS OF SAID METAL WITH A GASEOUS OXIDIZER, THE IMPROVEMENT COMPRISING FORMING SAID METAL ATOMS BY EXPLOSIVELY SHOCKING A GROOVED METAL PLATE HAVING A PLURALITY OF RECTANGULAR GROOVES THEREIN TO PRODUCE JETS OF METAL VAPOR AND DIRECTING SAID JETS THROUGH SAID GASEOUS OXIDIZER.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
10 words
The method of claim 1 wherein said oxidizer is fluorine.
Claim 4
Dependent Claim
35 words
The method of claim 2 wherein said metal is selected from the class consisting of Li, C, Mg, Al, Ti, V, Fe, Ni, Cu, Zn, Zr, Mo, Ag, Ta, W, Pt, Au, Pb, and U.
Claim 5
Dependent Claim
89 words
A chemical laser which comprises (a) an optical resonant cavity, (b) enclosure means for containing a gaseous oxidizer within said cavity, (c) a gaseous oxidizer contained within said cavity, (d) a grooved metal plate having a plurality of rectangular grooves therein adjacent to said cavity and in substantially parallel relationship thereto, and (c) means for explosively shocking said grooved metal plate to direct metal jets from said grooves in said plate through said oxidizer in said cavity to form molecules containing said metal and having a population inversion therein.
Claim 6
Dependent Claim
89 words
A chemical laser which comprises (a) an optical resonant cavity, (b) enclosure means for containing a gaseous oxidizer within said cavity, (c) a gaseous oxidizer contained within said cavity, (d) a grooved metal plate having a plurality of rectangular grooves therein adjacent to said cavity and in substantially parallel relationship thereto, and (c) means for explosively shocking said grooved metal plate to direct metal jets from said grooves in said plate through said oxidizer in said cavity to form molecules containing said metal and having a population inversion therein.
Claim 7
Dependent Claim
25 words
The laser of claim 4 wherein said grooved metal plate forms a wall of said enclosure means for containing a gaseous oxidizer within said cavity.
Claim 8
Dependent Claim
34 words
The laser of claim 5 wherein said grooved plate is exterior to said optical cavity and the plate standoff distance to cavity diameter ratio substantially equals the plate free surface to jet velocity ratio.
Claim 9
Dependent Claim
40 words
The laser of claim 4 wherein said oxidizer is F.sub.2 and said metal is selected from the class consisting of Li, C, Mg, Al, Ti, V, Fe, Ni, Cu, Zn, Zr, Mo, Ag, Ta, W, Pt, Au, Pb, and U.
