  • Abstract
    The performance of a CO2 laser was improved by coating the inside wall of the discharge tube with a discontinuous gold film. In the presence of the discharge, the gold acts as an ambient temperature catalyst to reform decomposed CO2. The gold coated laser delivered 122 W/m for both sealed-off and flowing operation. CO2 decomposition levels are presented as a function of input power, gas pressure, and temperature. Atomic oxygen, generated by the discharge, appears to be required for gold to exhibit any detectable catalytic activity
