Automatic impedance matching and opto-Hertzian effect in RF excited CO2 waveguide lasers

We report the successful operation of a novel automatic impedance matching technique (AIMing) and observations of the opto-Hertzian effect. The AIMing system is capable of maintaining efficient RF power delivery to a CO2 waveguide laser over a wide range of operating conditions. The opto-Hertzian signal, produced by circulating laser power fluctuations and detected in the RF reflected power, has some interesting properties and may be used for laser frequency stabilisation.
