| Abstract: | We report the design and performance characteristics of a carbon dioxide laser excited by a radial radiofrequency static gas discharge. Power extraction of 20 W is obtained using a multipass optical system, matched to a 13 cm long annular discharge gain region, within a linear stable resonator. |
