Abstract
We describe a modified design of a continuous-flow cw CO laser with lo ngitudinal electric discharge using an externally ribbed wall cooled d ischarge tube. The transverse ribbed discharge tube provides a more in tense heat exchange of the GO-laser gas with the walls. With this conf iguration it was possible to obtain about 50% more output power from a n all-line CO Delta upsilon = 1 laser. For a CO-overtone Delta upsilon = 2 laser we were able to improve both the output power and the numbe r of lines as compared to a conventional smooth tube.
