Abstract

Characteristics of CW CO laser with supersonic gas flow are discussed. Radio frequency discharge CO overtone (V+2→V) lasing with output power 50 W was demonstrated with gas cooling due to supersonic expansion. The overtone lasing was observed on 9→7, 10→8 and 11→9 vibrational transitions within spectral range 2.6-2.7 μm. The laser active medium length was 10 cm. The small signal gain on the overtone transitions was estimated to be 0.1 m^-1. Fundamental band (V+1→V) lasing was observed within 4.9 - 5.7 μm spectral range. In fundamental band output power 2.1 kW with efficiency 21% was obtained, with typical small signal gain being about 1 m^-1. Modeling experiments on electron-beam sustained discharge facility were carried out at experimental conditions (gas pressure, temperature) corresponding to those of supersonic gas flow. Possibilities of supersonic overtone CO laser design improvement to obtain overtone lasing on highly excited vibrational transitions of CO molecule corresponding to the spectral range ~3-4 micron are discussed.
