Abstract : This patent describes an electric discharge gas-dynamic laser (EDGDL) providing laser action in CO2 at 16 microns between the (02 0) and (01'0) levels as well as between the (10 0) and (01 0) levels at 14 micorns. A 9 micrometers or 10 micrometers saturating pulse equilibrates the (001) level with either the (02 0) or (10 0) level and creates the 14 micrometers or 16 micrometers inversion. Extraction efficiencies of 50% have been achieved. Repetition frequencies of 200HzZ have been achieved using a repetitively Q-switched cavity. (Author)
