High-pressure transverse-discharge CO laser

Experiments with a high-pressure transverse-discharge CO laser are described. The pulsed laser output was observed to occur on several CO rotational-vibrational transitions in bands from
\upsilon = 6 \rightarrow \upsilon = 5
to
\upsilon = 11 \rightarrow \upsilon = 10
. A study of the laser delay time versus CO pressure is presented and its relation to two inversion schemes is discussed in detail.
