An earlier model developed by others to study the 10.6-..mu..m laser transition in CO/sub 2/ has been extended for studying the 16-..mu mu.. (02/sup 0/0)..-->..(01/sup 1/0) laser transition in cold CO/sub 2/. The rate equations take into account the rotational relaxation and collisional transfer of population among (02/sup 0/0), (10/sup 0/0), and (02/sup 2/0) levels of CO/sub 2/. The model has been used to study the effect of various parameters on the 16-..mu..m output. It has been found that at higher pressures the collisional relaxation of the (02/sup 0/0) level can be overcome by application of a more powerful 9.6-..mu..m pulse to achieve an inversion between the (02/sup 0/0) and (01/sup 1/0) levels of CO/sub 2/. It is predicted that if transverse excitation is used in these cold mixtures, pulsed powers in excess of 100 kW could be obtained on 16 ..mu..m.
