Abstract
A closed loop carbon dioxide laser system includes a catalytic converter in the form of a conduit with an annular recess which is filled with a catalyst of platinum-plated alumina pellets that are externally heated.
Claims6
A closed-loop carbon dioxide laser system comprising:
- a carbon dioxide laser;
- a heat exchanger;
- a catalytic converter comprising a conduit means for conducting a gas, a catalysing means, said catalysing means having an annular recess in said conduit means, a plurality of pellets of platinum-plated alumina in said annular recess and porous means for containing said pellets in said annular recess, a heating means, for heating said catalysing means and turbulating means for deflections a portion of the gas towards said catalysing means;
- and conduit means for interconnection of said laser, said heat exchanger and said catalytic converter in a closed loop.
1 more element
