Abstract :
A high-power closed-cycle 1 kHz transversely excited atmospheric (TEA) CO2 laser with an efficient catalytic CO2 regenerator was used to investigate the variations of the average laser output power and the concentrations of the CO2, CO, and O2 molecules in the laser gas mixture with the operational performance of the CO2 regenerator. It was experimentally shown that for the laser gas mixture of CO2-N2-He=15-15-70% and the output coupler reflectivity of 70%, η of 0.1 was required to maintain the laser output power greater than 90% of the initial laser output power of 570 W at an input energy density and a clearing ratio of 150 J/L and 3.0, respectively
