  • Abstract
    Frequency stabilization of a RF excited CO2 laser on the peak of the Doppler broadened gain curve using the photoacoustic effect generated from the laser itself is achieved. The photoacoustic signal is directly coupled from a RF discharge chamber using a condenser microphone into an amplifier and a lock-in stabilizer. The frequency stability is estimated to be better then 3×10-8.
