Paper Abstract

A discharge cell has been used to simulate conditions in fast flow, radio-frequency excited CO2 lasers using dielectric electrodes. The frequency dependence of the discharge structure and the Alpha to Gamma transition has been observed in the range 13 - 40MHz. The radio frequency, the thickness of the dielectric layer, and the parallel capacitance of the matching circuit are all shown to control the discharge uniformity and excitation conditions at the centre of the discharge.
