Abstract
Frequency stabilization of a rf excited CO2 laser on the peak of the Dopple r broadened gain curve using the optogalvanic effect generated from the las er itself is achieved. The optogalvanic signal is directly coupled from a r f discharge chamber via a capacitor into a detector and a lock-in stabilize r. The frequency stability is estimated to be better then 3 x 10(-8).
