Calculations of the vibrational relaxation kinetics of carbon dioxide in a Co/sub 2/--Ar mixture expanding through a slit into a vacuum are used to evaluate the feasibility of using gasdynamic thermal pumping to obtain lasing between the levels of paired CO/sub 2/ modes. It is shown that the gain due to the (03/sup 1/ 0) -- (100) transition in CO/sub 2/ may reach 0.1 cm/sup -1/ and, at the optimal heating tempertures for a CO/sub 2/:Ar=1:1 mixture (T/sub i/approx. =1500 /sup 0/K), the thermal energy conversion efficiency in the gasdynamic laser may be 12%.
