Stimulated emission from the B$sup 2$$Sigma$ state of CO$sup +$ has been observed as a consequence of the charge transfer reaction between He$sup +$$sub 2$ and CO in the afterglow of a Febetron 706 discharge into 3 atm of helium containing 1.0 Torr of carbon monoxide. Peak gains of the order of 0.08 cm$sup - 1$ were found for the (0,2) vibrational component of the B$sup 2$$Sigma$$Yields$$X$$sup 2$$Sigma$ transition at 2470 A by directly measuring the time-resolved amplification of suitably filtered light from a xenon flashlamp. Correspondingly smaller gain, persisting for several hundred nanoseconds, was found for the (0,0) and (0,1) vibrational components of the B$sup 2$$Sigma$$Yields$$A$$sup 2$Pi transitions at 3954 and 4210 A, respectively.
