“…The only previous measurements of the effect of xenon on the electron density in a CO laser mixture have been reported by Baranova et a1 (1974). They used a microwave cavity resonant frequency method at -3230 MHz (Novgorodov et al 1971) with a relatively wide bore tube (2 cm), added 0 2 to all mixtures investigated, used comparatively low total gas pressures (< 13 Torr) and only added 1 Torr of xenon. We have used a similar technique at N 9000 MHz with mixtures and pressures appropriate to the most efficient operation of sealed CO-He-Xe lasers.…”

The mechanism responsible for the effectiveness of xenon addition on the room temperature operation of sealed CO-He CW gas lasers is investigated with electron density, discharge potential and small-signal gain measurements. It is established that the discharge impedance is lowered, the electron density increased and the gas heating decreased, but there is no need to postulate a change in the electron distribution function. One causal sequence explains all the xenon addition results and also the effects of the addition of argon and krypton.
