Abstract
In materials processing such as cutting, welding, and surface treatment, higher processing efficiencies have been demonstrated with the CO laser when compared with the CO2 laser.1,2 It can be attributed to the shorter output wavelength of the CO laser which leads to higher Fresnel absorption and/or lower plasma absorption loss of the laser energy. But the need for cryogenic cooling of the laser gas has long been a discouraging issue in the practical use of CO laser. However, lately some high-power (> 100 W), room temperature operations of CO laser have been reported.3,4 We have demonstrated successful room temperature CO-laser operation with a fast-axial-flow, rf-discharge excitation scheme.5
