Paper Abstract

A study of RF discharge for CO2 lasers is made on the basis of RF discharge theory. The relation among dimension of potential fall area, excitation frequency, gas pressure and other parameters is given. The relation among dimension of central dim area, excitation frequency and other parameters is given as well. The study shows dimension of potential area to contract with increasing excitation frequency and gas pressure; dimension of central dim area increases when excitation frequency and gas pressure increases. These results are consistent with experimental results. In the first type of RF discharge, the central dim area is not plasma. In the second type of RF discharge, the central bright area is plasma.
