I claim:
1. A method for the production of the excited radical, CS*, by irradiating CSCl.sub.2 in admixture with O.sub.2 to produce CO in an excited vibrational state which lases, and method comprising:
(i) preparing a homogeneous admixture of CSCl.sub.2 and O.sub.2 ;
(ii) metering said admixture of CSCl.sub.2 and O.sub.2 into a properly conditioned laser cell to achieve a predetermined pressure from about 15 to about 100 torr; and
(iii) irradiating said admixture of CSCl.sub.2 and O.sub.2 for a predetermined time period with the R.sub.(48) (992 cm.sup.-1) line of a tunable cw CO.sub.2 multiline laser operating at a predetermined power level to effect dissociation of CSCl.sub.2 to produce the excited radical, CS*, which immediately react with O.sub.2 present to produce CO in an excited vibrational state which lases.
2. The method of claim 1 wherein said predetermined pressure of said CSCl.sub.2 and said O.sub.2 is about 15 torr each in said admixture; said predetermined power level of said tunable cw CO.sub.2 multiline laser is about 100 watts; and wherein said predetermined time of irradiating is about one second.
