Abstract
Temporal behavior of small signal gain (SSG) in pulsed CO laser operating on oxygen rich gas mixtures CO:He:O2=1:4:X and CO:N2:O2=1:9:X was studied experimentally. The rich content of oxygen (X≥2) in these mixtures resulted in significant increase of the maximum gain on low (6≤V≤13) vibrational transitions V+1→V and strong absorption on high ones (V≥18). Both fundamental and first overtone CO lasing on these gas mixtures were studied. The threshold energy input is demonstrated to be diminished at addition of O2 for pulsed EBSD CO-laser operating on either fundamental or overtone transitions, with maximum laser efficiency increasing. It is shown that pulsed EBSD CO-laser can effectively operate on air-containing gas mixtures.
