Paper Abstract

High pressure operation of a fast-axial-flow CO2 laser, with a rectangular cross-section RF slab discharge is demonstrated in both cw and pulsed modes. Spatially resolved measurements of discharge power densities give good agrement with total input powers while calculated values of sheath thickness correspond with visual observations of the gas discharge. Variations in power density and sheath thickness along the gas flow axis are interpreted in terms of pressure gradients and gas flow choking within the discharge.
