Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
72 words
A laser system comprising, a gas laser structure including a laser cavity filled with a gaseous laser active material, said laser active material including a mixture of a majority gas and a minority gas, said mixture being chosen from the group consisting of Ne-N 2 where Ne is the majority gas and He-CO where He is the majority gas, and radiation means for providing ionizing radiation to said gaseous laser active material.
Claim 2
Dependent Claim
72 words
A laser system comprising, a gas laser structure including a laser cavity filled with a gaseous laser active material, said laser active material including a mixture of a majority gas and a minority gas, said mixture being chosen from the group consisting of Ne-N 2 where Ne is the majority gas and He-CO where He is the majority gas, and radiation means for providing ionizing radiation to said gaseous laser active material.
Claim 3
Dependent Claim
13 words
The system of claim 1 wherein said mixture is of Ne-N 2 .
Claim 4
Dependent Claim
22 words
The system of claim 2 wherein the concentration of N 2 in Ne in said mixture is between 0.01 and 1/2 percent.
Claim 5
Dependent Claim
63 words
The system of claim 3 wherein said radiation means includes fissionable material and a neutron source, said fissionable material being responsive to neutrons from said neutron source to generate ionizing radiation which is incident on said laser active material, the neutron flux density from said neutron source developing sufficient ionizing radiation from said fissionable material for said laser active material to reach threshold.
Claim 6
Dependent Claim
25 words
The system of claim 4 further including gas-handling means coupled to said laser cavity for maintaining the desired pressure of said gaseous laser active material.
