RF system of a 1kW level fast axial flow CO2 laser

In our RF-excited 1kW level fast axial flow CO2 laser,8 laser discharge tubes are driven by a single RF power source through a 50Ωtransmission line and a π-type matching networks,With this arrangement tatal 15kW continuous wave RF power has been effectively and uniformly coupled to discharge plasma within 8 tubes,The key task of this technique is RF impedance matching.
