Abstract
CW laser oscillation has been observed on twenty-eight vibration–rotation transitions in the range 5.22–5.55 µm with a CO chemical laser. This is the first report of purely CW lasing in chemically excited CO, although we have previously1 announced a “quasi-CW” laser of this type in which the duration of the laser pulse is longer than the characteristic decay time of excited CO. We give here the resolved laser spectra and show that long term CW operation can be achieved in a CO chemical laser with rather modest requirements for pump speed and input energy.
