Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
In a DF or HF chemical laser having a gas mixing region, a resonant cavity, a gas exhaust region, means for introducing a first fluorine gaseous reactant into said mxing region, and means for introducing a second gaseous reactant selected from the group consisting of HF and DF into said mixing region, the improvement which comprises means for the cold storage of an NF 3 gaseous component capable of generating said first fluorine gaseous reactant, means for preheating said stored gaseous component, means for effecting the dissociation of said preheated gaseous component to fluorine, means for cooling said dissociated gaseous fluorine, and means for presenting said cooled, dissociated, gaseous fluorine to said gas mixing region.
Claim 2
Dependent Claim
115 words

Claim 3
Dependent Claim
24 words
A chemical laser in accordance with claim 1 wherein said dissociation means includes a regenerative heat exchange means positioned downstream from said exhaust means.
Claim 4
Dependent Claim
21 words
A chemical laser in accordance with claim 2 further including a combustor means in association with said regenerative heat exchange means.
