Title: CO Chemical laser produced by laser induced chemistry of CSCl.sub.2

Abstract: The R.sub.(48) (992 cm.sup.-1) line of a tunable cw multiline CO.sub.2 laser is used to dissociate thiophosgene (CSCl.sub.2) to produce the excited radical, CS*, homogenously in a laser chamber containing premixed O.sub.2. The R.sub.(48) (992 cm.sup.-1) line of the CO.sub.2 laser is resonant with the 2.nu..sub.2 (992 cm.sup.-1) overtone of CSCl.sub.2. This line is strongly absorbed by the CSCl.sub.2 which dissociates (80%) into 2 Cl and CS*. The CS* reacts with the premixed O.sub.2 to chemically produce excited CO which subsequently lases.
