Abstract
Stimulated emission from the B2Σ state of CO+ has been observed as a consequence of the charge transfer reaction between He+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−1 were found for the (0,2) vibrational component of the B2Σ→X2Σ transition at 2470 Å 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 B2Σ→A2Π transitions at 3954 and 4210 Å, respectively.Keywords
