Nuclear pumping of a carbon monoxide laser

Abstract

It is shown that plasma-chemical processes involving ionized and excited particles can make the main contribution to the pumping of energy into vibrations of carbon monoxide molecules. It is noted that the use of helium as a buffer gas in the active laser medium is not optimal. The employment of argon instead of helium permits a 1.5-fold increase in the efficiency of the pumping of energy into carbon monoxide molecules and an order-of-magnitude decrease in the threshold energy for pumping the active medium.
