ABSTRACT:
An electric discharge gas-dynamic laser (EDGDL) providing laser action in CO.sub.2 at 16 microns between the (02.degree.0) and (01'0) levels as well as between the (10.degree.0) and (01'0) levels at 14 microns. A 9.mu. or 10.mu. saturating pulse equilibrates the (001) level with either the (02.degree.0) or (10.degree.0) level and creates the 14.mu. or 16.mu. inversion. Extraction efficiencies of 50% have been achieved. Repetition frequencies of 200Hz have been achieved using a repetitively Q-switched cavity.
