Abstract

We stabilized a frequency and a power of RF excited CO₂ laser to the centers of the Doppler broadened gain curves using a photoacoustic effect generated from the laser itself. The frequency stability is estimated to be better than of 5.4x10^-8 and power variation is greatly improved to 9%. We suggest that this method can be applied for frequency and power stabilization of other kinds of RF excited laser, for example Xe and CO laser.
