Abstract

An original aerodynamic technique has been developped to achieve stable and uniform dc-discharges in wide rectangular channels. The discharge is spread out over the width of the laser channel by using parallel turbulent transverse flows (TTF). The technique insures stability and uniformity of the discharge without the need of a fine segmentation of the electrodes. Various experiments have been carried out in open and closed- gas cycles. At a pressure of 50 mbar, discharge power loading up to 6 W/cm3 has been obtained for a differential pressure limited to about 10 mbar. Experimental results are presented along with the design of a 3-kW laser.
