ABSTRACT:
A device and process using a gold as a catalyst for oxidizing carbon monoxide to form CO.sub.2 at ambient temperatures. This has particular application to CO.sub.2 lasers. In one CO.sub.2 laser embodiment, gold is distributed on the walls of the discharge volume. The gold is divided to form electrically isolated islands to prevent interference with the discharge. Energetic forms of oxygen, such as atomic oxygen reacts with CO on the gold catalyst. In another embodiment, the gold catalyst is used in a convective flow laser.
