Abstract
Spectrally resolved atmospheric absorption has been investigated to determine the problems of long path beam delivery of high power industrial CO laser light for material processing. A dry gas purged beam path is found to be essential if the natural CO laser spectrum is used. However, an unpurged beam delivery system may be satisfactory over typical distances when the spectrum is modified to avoid coincidence with strong water lines by the use of an intra- cavity absorption section.
