Paper Abstract

The outstanding potential of radio-frequency discharges for the excitation of high power CO2-lasers has been demonstrated for fast axial flow and transverse flow lasers. Outcoupled optical power densities up to 5 W/cm3 have been obtained with nearly diffraction limited beam quality. Good beam quality has been achieved for cw as well as for pulsed mode operation by applying a double pass unstable resonator in the transverse flow laser.
